Re: Library directory missing in pkg-config files

Hi Thomas,
Thanks for your reply.

I'm not passing any custom linker options. I'm just setting the install prefix.
Here is a minimal example that shows the problem on a fresh debian bullseye
system:

 docker run -it --rm debian:11
 apt update && apt install -y gcc make wget pkg-config
 wget -O ncurses.tar.gz
https://invisible-island.net/archives/ncurses/ncurses-6.3.tar.gz
 tar xf ncurses.tar.gz
 cd ncurses-6.3/
 mkdir -p /prefix-ncurses/pkgconfig
 env TERMINFO= TERMINFO_DIRS= ./configure --prefix=/prefix-ncurses
--with-termlib --without-shared --enable-pc-files
--with-pkg-config-libdir=/prefix-ncurses/pkgconfig
 make -j$(nproc)
 make install
 cd /tmp
 echo -e '#include <ncurses.h>\nint main(void) { initscr(); }' > app.c
 export PKG_CONFIG_PATH=/prefix-ncurses/pkgconfig
 gcc $(pkg-config --cflags ncurses) app.c $(pkg-config --libs ncurses)
 # /usr/bin/ld: cannot find -lncurses
 # /usr/bin/ld: cannot find -ltinfo
 # collect2: error: ld returned 1 exit status
 grep Libs: /prefix-ncurses/pkgconfig/ncurses.pc
 # Libs:  -lncurses -ltinfo

Sorry! I just provided the options in the example above.

This is an auto-generated script. Should I post the whole file here?
Perhaps configuration summary will be sufficient?
