Crosscompiling ECL for Windows

Dear ECL-developers, Can one crosscompile ECL for Windows (on a Linux based system)? Currently it fails - both the latest release and the current GIT - with: $ ./configure --host=i686-w64-mingw32 $ make [...] i686-w64-mingw32-gcc -DECLDIR="\"/usr/local/lib/ecl-16.1.2\"" -I. -I/tmp/ecl/build -I/tmp/ecl/src/c -I../ecl/gc -DECL_API -DECL_NO_LEGACY -g -O2 -D_THREAD_SAFE -Dmingw32 -c -o threads/process.o threads/process.o.c /tmp/ecl/src/c/threads/process.d:40:22: error: conflicting types for 'GC_CreateThread' extern HANDLE WINAPI GC_CreateThread( ^ In file included from /tmp/ecl/build/ecl/config.h:84:0, from /tmp/ecl/build/ecl/ecl.h:37, from /tmp/ecl/src/c/threads/process.d:20: /tmp/ecl/build/ecl/gc/gc.h:1536:26: note: previous declaration of 'GC_CreateThread' was here GC_API HANDLE WINAPI GC_CreateThread( ^ /tmp/ecl/src/c/threads/process.d: In function 'mp_exit_process': /tmp/ecl/src/c/threads/process.d:604:1: warning: 'noreturn' function does return Makefile:85: recipe for target 'threads/process.o' failed make[2]: *** [threads/process.o] Error 1 make[2]: Leaving directory '/tmp/ecl/build/c' Makefile:120: recipe for target 'libeclmin.a' failed make[1]: *** [libeclmin.a] Error 2 make[1]: Leaving directory '/tmp/ecl/build' Makefile:70: recipe for target 'all' failed make: *** [all] Error 2 What is the problem here? (Background: I developed a crosscompiled Windows installer for the (Lisp based) computer algebra system 'Maxima' (using 'Wine' (does ECL work with the emulator 'wine'?)), currently based on CLISP and SBCL - and probably I can support ECL too - but for that I should be able to crosscompile it. Best regards, Wolfgang

ECL build and SHELL variable.
by Tigran Aivazian 27 Sep '16

Dear Yasuaki, I have some good news --- I have successfully compiled ECL 16.1.2 under Termux environment and then successfully compiled MAxima 5.38.1 based on it. This is Android 5.1.1 running on Nexus 10 tablet, i.e. armv7l architecture. I intend to also compile it on Android 6.0.1 on aarch64 architecture. I had to make a few changes to ECL which I will have to submit to the maintainer at some point. Now, everything (except the bits you noticed, like fib() etc which are worked around in your init.lisp file) works fine except the system() function (and invoking gnuplot which uses the same mechanism). I used strace to track it down to the fact that even though Maxima was compiled with "--posix-shell=/data/data/com.termux/files/usr/bin/bash", still the plot2d() command causes execve() with hardcoded path "/bin/sh". I have made sure that there are NO hardcoded instances of "/bin/sh" left in Maxima, BUT it still happens. This means it is coming from ECL and I see hardcoded "/bin/sh" here: $ strings /usr/local/lib/ecl-16.1.2/defsystem.fas | fgrep --color "/bin/sh" So I suspect it is coming from defsystem.fas. Now, you must have faced the same issue when you compiled ECL 12.12.1 for use by Maxima 5.36.1 on Android. But your sources on github don't contain any patches to ECL, so I am writing to you to ask how you overcame this issue (because running your maxima.pie binary in Termux works fine, but I wanted to have Maxima 5.38.1 and so I had to recompile everything from sources). I will dig into ECL sources today trying to find this hardcoded "/bin/sh" (it should really rely on the value of SHELL variable) but if you know the answer it would save my time greatly. Thank you. Kind regards, Tigran

Problems compiling ECL for Termux on Android.
by Tigran Aivazian 26 Sep '16

Hello, I am trying to compile ECL 16.1.2 under Android 6.0.1 in Termux environment (this has almost nothing to do with compiling for Android target --- just think of Termux as a GNU Linux implementation running on Android kernel). Termux is an Android application which provides GNU Linux environment, see here http://termux.com (After installing Termux do "apt update && apt upgrade -y" and also install a myriad of applications to turn it into proper Linux development workstation, e.g. I always install the following (plus a plethora of python modules but they are irrelevant for this discussion): apt install autoconf automake bc binutils-dev bison bzip2 cboard clang-dev cmake coreutils ctags curl cvs diffutils dnsutils dos2unix dpkg-dev ecj elfutils-dev \ elinks expect-dev fftw-dev ffmpeg-dev file-dev findutils flac flex-dev freetype-dev gawk-dev gcal gdb-dev git glib-dev glib-bin gnuchess gnuplot grep gzip htop iconv imagemagick-dev \ lftp libandroid-glob-dev openssh libtool-dev libpng libpng-dev libtiff libtiff-dev libtiff-utils ltrace strace mc man-dev make-dev \ lua-dev luarocks mlocate ncurses-dev ncurses-utils nmap patch p7zip php-dev pkg-config mpv procps python-dev qalc rsync sed tar taskwarrior tcl-dev termux-api \ tesseract-dev tmate tracepath tree units unzip unrar vim wget zip linux-man-pages but a smaller subset should be sufficient, e.g. surely one doesn't need gnuchess/cboard to compile ECL :) So, in order to configure ECL 16.1.2 I did the following after unpacking the sources: 1. $ export CONFIG_SHELL = $SHELL 2. Fix all configure and config.guess scripts to not use #!/bin/sh because under Termux the shell is $PREFIX/bin/bash (and /bin is not accessible): $ find -name 'configure' -exec termux-fix-shebang {} \; $ find -name 'config.guess' -exec termux-fix-shebang {} \; 3. $ ./configure --prefix=$PREFIX/local This succeeds. And so I go on to 4. $ make (this fails but due to a trivial thing --- some Makefiles contain hardcoded "/bin/sh" references --- so I fix all these to refer to the proper location of bash in Termux) 5. Re-run make after all these changes and it fails here: $ make cd build; make make[1]: Entering directory '/data/data/com.termux/files/home/Maxima/ecl-16.1.2/build' if (echo c gc libffi atomic | grep gmp); then \ cd gmp && make install && \ cd .. && mv include/gmp.h ecl/ && rmdir include && \ mv ./libgmp.a ./libeclgmp.a; \ fi test -d ecl/gc || mkdir ecl/gc test -d ecl/gc/private || mkdir ecl/gc/private if (echo c gc libffi atomic | grep gc); then \ cd gc && make install && cd .. && \ cp -rf /data/data/com.termux/files/home/Maxima/ecl-16.1.2/src/bdwgc/include/private/*.h ecl/gc/private/ && \ mv libgc.a libeclgc.a; \ fi c gc libffi atomic make[2]: Entering directory '/data/data/com.termux/files/home/Maxima/ecl-16.1.2/build/gc' make[3]: Entering directory '/data/data/com.termux/files/home/Maxima/ecl-16.1.2/build/gc' depbase=`echo dyn_load.lo | sed 's|[^/]*$|.deps/&|;s|\.lo$||'`;\ /data/data/com.termux/files/usr/bin/bash ./libtool --tag=CC --mode=compile gcc -fPIC -DHAVE_CONFIG_H -I./include -I/data/data/com.termux/files/home/Maxima/ecl-16.1.2/src/bdwgc/include -I./libatomic_ops/src -I/data/data/com.termux/files/home/Maxima/ecl-16.1.2/src/bdwgc/libatomic_ops/src -I/data/data/com.termux/files/home/Maxima/ecl-16.1.2/build/ecl -fexceptions -Wall -Wextra -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -g -O2 -fPIC -D_THREAD_SAFE -fno-strict-aliasing -MT dyn_load.lo -MD -MP -MF $depbase.Tpo -c -o dyn_load.lo /data/data/com.termux/files/home/Maxima/ecl-16.1.2/src/bdwgc/dyn_load.c &&\ mv -f $depbase.Tpo $depbase.Plo libtool: compile: gcc -fPIC -DHAVE_CONFIG_H -I./include -I/data/data/com.termux/files/home/Maxima/ecl-16.1.2/src/bdwgc/include -I./libatomic_ops/src -I/data/data/com.termux/files/home/Maxima/ecl-16.1.2/src/bdwgc/libatomic_ops/src -I/data/data/com.termux/files/home/Maxima/ecl-16.1.2/build/ecl -fexceptions -Wall -Wextra -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -g -O2 -fPIC -D_THREAD_SAFE -fno-strict-aliasing -MT dyn_load.lo -MD -MP -MF .deps/dyn_load.Tpo -c /data/data/com.termux/files/home/Maxima/ecl-16.1.2/src/bdwgc/dyn_load.c -o dyn_load.o /data/data/com.termux/files/home/Maxima/ecl-16.1.2/src/bdwgc/dyn_load.c:116:14: error: redefinition of 'link_map' struct link_map { ^ /data/data/com.termux/files/usr/include/link.h:57:8: note: previous definition is here struct link_map { ^ /data/data/com.termux/files/home/Maxima/ecl-16.1.2/src/bdwgc/dyn_load.c:123:14: error: redefinition of 'r_debug' struct r_debug { ^ /data/data/com.termux/files/usr/include/link.h:66:8: note: previous definition is here struct r_debug { ^ 2 errors generated. make[3]: *** [Makefile:1527: dyn_load.lo] Error 1 make[3]: Leaving directory '/data/data/com.termux/files/home/Maxima/ecl-16.1.2/build/gc' make[2]: *** [Makefile:1710: install-recursive] Error 1 make[2]: Leaving directory '/data/data/com.termux/files/home/Maxima/ecl-16.1.2/build/gc' make[1]: *** [Makefile:123: libeclgc.a] Error 2 make[1]: Leaving directory '/data/data/com.termux/files/home/Maxima/ecl-16.1.2/build' make: *** [Makefile:70: all] Error 2 So, then I check that those two definitions (link_map and r_debug) in dyn_load.c are compatible with the system ones in link.h and comment them out.

I am a Linux kernel developer (or was, many years ago) and know C and a bit of asm for x86 architecture, but not ARM. Any ideas? Btw, the reason I am trying to compile ECL for Termux is because the next step would be to compile Maxima. I know that there is already Maxima for Android but it is a GUI version and so not very convenient for the real work. Real scientific work with Maxima can only be done in a text-based terminal version (and plotting is irrelevant as it is much more convenient to be done with python's matplotlib anyway which works perfectly under Termux). Kind regards, Tigran
