tccbin

This is a prebuild tcc (git://repo.or.cz/tinycc.git), cut at commit 9eef339 .

It is compiled with:

./configure --prefix=/var/tmp/tcc --crtprefix=/var/tmp/tcc/lib:/usr/lib64:/usr/lib/x86_64-linux-gnu --libpaths=/var/tmp/tcc/lib:/usr/lib/x86_64-linux-gnu:/usr/lib64:/usr/lib:/lib/x86_64-linux-gnu:/lib:/usr/local/lib/x86_64-linux-gnu:/usr/local/lib  --debug

tccbin's Issues

change language tag from “Roff” to “C”

libgc.a for macos is built without `-mmacosx-version-min=10.7` breaking macos pre-12.0

Right now, using tcc (built from git) on macos 11 (or anything prior to 12.0) will fail with:

ld: warning: object file (/Users/x/d/v/thirdparty/tcc/lib/libgc.a(gc.o)) was built for newer macOS version (12.0) than being linked (10.7)
Undefined symbols for architecture x86_64:
  "____chkstk_darwin", referenced from:
      _GC_forward_exception in libgc.a(gc.o)
      _GC_mark_thread in libgc.a(gc.o)
ld: symbol(s) not found for architecture x86_64
clang-11: error: linker command failed with exit code 1 (use -v to see invocation)

This is resolved by rebuilding libgc.a and passing the -mmacosx-version-min=10.7, which matches what v itself is passing to tcc internally.

This specifically affects https://github.com/vlang/tccbin/tree/thirdparty-macos-amd64

I've worked around this locally by manually rebuilding libgc.a with these commands (from the tcc repo):

cc -mmacosx-version-min=10.7 thirdparty/libgc/gc.c -c -o gc.o
libtool -static -o thirdparty/tcc/lib/libgc.a gc.o

(tangential relation to vlang/v#16386)

Branch content is swapped.

Branch "thirdparty-windows-amd64" contains i386-win32-tcc.exe
thirdparty-windows-i386 contains x86_64-win32-tcc.exe

TCC build does not support non latin symbols on the path

This is a compiler bug, please report it using `v bug file.v`.

After moving the v src file to something like "C:\learning\v" error doesnt occurred, no Вася allowed.

Add RegDeleteValueW to lib/advapi32.def

sokol/sounds examples in V repo cannot be compiled with tcc-amd64

I have a vague impression that compilation used to be successful X months ago.

On branch thirdparty-freebsd-amd64 buildtcc.sh needs a fix

A linking failure, at least with the latest tcc (4410dbd):

cc -o tcc tcc.o libtcc.a -lm -lpthread -g
ld: error: undefined symbol: tcc_new
>>> referenced by tcc.c:283
>>>               lto.tmp:(main)

etc. The following fixes it:

diff --git a/buildtcc.sh b/buildtcc.sh
index 32faa74..81bc042 100644

Ideally the script should exit 1 when any step fails rather than try to copy things in v/thirdparty/tcc
