It's difficult to compile on msys2 ucrt64

[Q191]

export PATH=$PATH:xxx/v/bin
pacman -S mingw-w64-ucrt-x86_64-toolchain mingw-w64-ucrt-x86_64-git
v up
v update --all

pacman -S mingw-w64-ucrt-x86_64-freetype mingw-w64-ucrt-x86_64-harfbuzz mingw-w64-ucrt-x86_64-fribidi mingw-w64-ucrt-x86_64-fontconfig mingw-w64-ucrt-x86_64-pango  mingw-w64-ucrt-x86_64-glib2

I need to compile demo like this：

# pkg-config.exe --cflags --libs pango glib-2.0 freetype2 fribidi fontconfig  | sed 's/xxx/ /g' | sed 's/[ ]-I /:/g'

C_INCLUDE_PATH="/ucrt64/include/pango-1.0:/ucrt64/include/cairo:/ucrt64/include/pixman-1:/ucrt64/include/fribidi:/ucrt64/include/freetype2:/ucrt64/include/libpng16:/ucrt64/include/harfbuzz:/ucrt64/include/glib-2.0:/ucrt64/lib/glib-2.0/include:$C_INCLUDE_PATH" \

v -cc gcc run examples/form_validation.v

Thanks for the report. Could you please provide the following information:

• The complete output of the failing V command
• The output of v doctor
• The output of echo $MSYSTEM, echo $MINGW_PREFIX, and echo $PKG_CONFIG_PATH
• The output of where.exe gcc and where.exe pkg-config
• The output of pkg-config --cflags --libs pango pangoft2 glib-2.0 freetype2 fribidi fontconfig
• The failing command rerun with -showcc

Please also confirm whether the command is being run from the MSYS2 UCRT64 shell.

Moreover, compilation is slow, and the generated binary files are very large, even without using static linking.

The IME is malfunctioning on Windows: the cursor does not follow the input, and input is not committed in batches (e.g., typing "我们" results in only "们" being committed); furthermore, deleting characters removes ones that have already been committed to the text.

[GGRei]

Ok, the report actually covers several separate issues:

• V's internal pkg-config implementation does not apply MSYS2 prefix relocation correctly. It turns /ucrt64 into paths such as C:\ucrt64, while your actual installation is under D:\TOOL\msys2\ucrt64.
• The default build first tries TCC and then retries with GCC. The reported shobjidl.h error comes from TCC, while the real GCC error is currently hidden.
• Windows IME composition is not implemented end-to-end yet. This will require coordinated changes in V/gg, vglyph, and gui.
• The compilation time and executable size may be affected by gui pulling in networking and TLS dependencies, but more measurements are needed before calling that a performance regression.

To complete the build diagnosis, could you please run this final command and paste its complete output?

env -u CPATH -u C_INCLUDE_PATH v -cc gcc -no-retry-compilation -showcc -show-c-output fractional_size_demo.v

This will isolate GCC and reveal the actual error without the TCC retry hiding it.
