Lex/Yacc files aren't compiled in IDE generated files.

[IsaccBarker]

Xmake Version

v2.7.8+master.025fbe955

Operating System Version and Architecture

macOS Ventura 13.2

Describe Bug

Take the example Lex and Yacc project located at /tests/projects/lex_yacc. If you compile it with just Xmake, it runs fine. However, if you try and generate a Makefile or CMakeLists.txt file to compile it with (with xmake project -k makefile or xmake project -k cmake), it compile the source that lex or yacc spit out.

In fact, in the generated build files, it doesn't even attempt to link against them, or even invoke the tools in the first place. The only thing it does is include the directory where Xmake in theory told yacc to output the header file.

Expected Behavior

A successful compilation.

As you can see, the Makefile doesn't even mention yacc or lex, with the exception of including build/.gens/calc/macosx/arm64/release/rules/yacc_yacc.

I have improved cmake generator, you can try it again.

xmake update -s github:xmake-io/xmake#cmakelists
xmake project -k cmake
mkdir build
cd build
cmake ..
make

The makefile generator still needs a lot of work and is not supported yet, I will improve it in the future.

[IsaccBarker]

Ah, sorry, didn't know that the makefile generator wasn't finished. Was it in the docs and I just missed it?

Otherwise, it seems to work fine, thanks for the quick response :)

[waruqi]

I just fixed cmake generator, not makefile
