Can't compile on Debian aarch64

[Cicorione]

Hi @pgundlach,

I got stuck here when I try to compile on aarch64:

SDPRO=yes rake buildlib
go install -ldflags "-X main.basedir=/home/cicorione/git/publisher -s"  speedatapublisher/sphelper/sphelper
/home/cicorione/git/publisher/bin/sphelper buildlib

Thanks… 🙏

I think that ccenv has no valid entry for this case in buildlib.go. You need to set the environment variable

CC_" + goarch + "_" + goos

in your case probably CC_ arm64_linux

to a path to clang or cc.

[Cicorione]

Hi Patrick, I didn't really understand what you wrote, but it looks like that arm64 is already contemplated, I found this:

        switch goarch {
        case "amd64":
            cmd = exec.Command(ccenv, "-shared", "-fPIC", "-o", filepath.Join(dylibbuild, "luaglue.so"), "luaglue.c", "-I/usr/include/lua5.3/")
        case "arm64":
            cmd = exec.Command(ccenv, "-shared", "-fPIC", "-o", filepath.Join(dylibbuild, "luaglue.so"), "luaglue.c", "-I/usr/include/lua5.3/")
        }

🤔

[pgundlach]

Sorry. Set the environment variable CC_arm64_linux to some kind of c-compiler (clang or cc). For example I have

export CC_arm64_linux=/usr/bin/aarch64-linux-gnu-gcc

in my setup. Then run rake buildlib.

[Cicorione]

Thank you, it worked! 🙏

Unfortunately I found another obstacle, here my steps:

$ export CC_arm64_linux=/usr/bin/aarch64-linux-gnu-gcc
$ export CGO_CFLAGS="-I /usr/include/texlua53"
$ publisher ) SDPRO=yes rake build

go install -ldflags "-X main.basedir=/home/cicorione/git/publisher -s"  speedatapublisher/sphelper/sphelper
/home/cicorione/git/publisher/bin/sphelper build
build pro

$ SDPRO=yes rake buildlib

go install -ldflags "-X main.basedir=/home/cicorione/git/publisher -s"  speedatapublisher/sphelper/sphelper
/home/cicorione/git/publisher/bin/sphelper buildlib
arm64
Building dynamic library for linux arm64
Building dynamic lua glue library for linux arm64

then

~/git/publisher/bin/./sp --layout=idx.xml --jobname=idx04 --runs=2
Run speedata publisher 4.19.20 (Pro)
Can't find sdluatex binary

What's wrong now? 😭

[Cicorione]

Hi Patrick I tried with your binary but it looks like it is for AMD64 architecture... I had a similar issue with FreeBSD, I believe I need to create a symlink to /usr/bin/sdluatex, this is what I have installed:

locate lua53
/usr/include/texlua53
/usr/include/texlua53/lauxlib.h
/usr/include/texlua53/lua.h
/usr/include/texlua53/lua.hpp
/usr/include/texlua53/luaconf.h
/usr/include/texlua53/lualib.h
/usr/lib/aarch64-linux-gnu/libtexlua53.a
/usr/lib/aarch64-linux-gnu/libtexlua53.so
/usr/lib/aarch64-linux-gnu/libtexlua53.so.5
/usr/lib/aarch64-linux-gnu/libtexlua53.so.5.3.6
/usr/lib/aarch64-linux-gnu/pkgconfig/lua53-c++.pc
/usr/lib/aarch64-linux-gnu/pkgconfig/lua53.pc
/usr/lib/aarch64-linux-gnu/pkgconfig/texlua53.pc
/usr/share/doc/libtexlua53-5
/usr/share/doc/libtexlua53-5/changelog.Debian.gz
/usr/share/doc/libtexlua53-5/changelog.gz
/usr/share/doc/libtexlua53-5/copyright
/var/lib/dpkg/info/libtexlua53-5:arm64.list
/var/lib/dpkg/info/libtexlua53-5:arm64.md5sums
/var/lib/dpkg/info/libtexlua53-5:arm64.shlibs
/var/lib/dpkg/info/libtexlua53-5:arm64.triggers

Perhaps /usr/lib/aarch64-linux-gnu/libtexlua53.so to /usr/bin/sdluatex 🤔

[Cicorione]

I solved it:

1. sudo ln -s /usr/bin/luatex /usr/bin/sdluatex
2. export CC_arm64_linux=/usr/bin/aarch64-linux-gnu-gcc
3. export CGO_CFLAGS="-I /usr/include/texlua53"
4. rake build
5. rake buildlib

Maybe you can change the instruction to look for sdluatex and luatex... 🤔

Thanks! 🙏
