Describe the bug

Building compiler in release mode fails.

Reproduction Steps

Try building with the following:

make
v -prod self

instead of make -f GNUmakefile The GNUmakefile is mainly for *BSD systems, that need to use gmake instead of make.

Ok, thanks. Will try that.

[> Try building with the following:

make

passes as

cd ./vc && git clean -xf && git pull --quiet
cd ./thirdparty/tcc && git clean -xf && git pull --quiet
cc  -std=gnu99 -w -o v1.exe ./vc/v.c -lm -lpthread 
./v1.exe -no-parallel -o v2.exe  cmd/v
./v2.exe -nocache -o ./v  cmd/v
rm -rf v1.exe v2.exe
Your `tcc` is working. Good - it is much faster at compiling C source code.
V has been successfully built
V 0.4.4 45e13ea

but

./v -prod self

then fails as

V self compiling (-prod -o v2)...

. Need help.

Note that I need to compile with full optimizations in order get fair benchmarks at when rerunning and updating the table at https://gitlab.com/per.nordlow/compiler-benchmark.

I pulled down a docker image of ubuntu 22.04, installed git and build-essential, then did the following

Note that there were no errors at all - v -prod self worked fine.

This implies there is something else going on with your system that is preventing V from compiling properly.

Ok, thanks for looking into it anway.

Have you tried deleting the repository directory and cloning it again,
Maybe that GNUmakefile did something irreversible.

[JalonSolov]

Also delete ~/.vmodules/cache to make sure no cached values are interfering.
