Meson support

[QWERTIOX]

Hi, i trying to add meson support QWERTIOX@87df127 so i can add it to wrapdb but i get weird linking errors

I'm confused how even cmake based builds see these functions from different translation units without including headers. My configuration:

i'm not sure what your question is? i'm sorry, but i know very little about meson.

[dankamongmen]

so this is the command that's blowing up:

clang-18  -o libnotcurses.so libnotcurses.so.p/src_lib_gpm.c.o libnotcurses.so.p/src_lib_in.c.o libnotcurses.so.p/src_lib_kitty.c.o libnotcurses.so.p/src_lib_layout.c.o libnotcurses.so.p/src_lib_linux.c.o libnotcurses.so.p/src_lib_menu.c.o libnotcurses.so.p/src_lib_metric.c.o libnotcurses.so.p/src_lib_mice.c.o libnotcurses.so.p/src_lib_notcurses.c.o libnotcurses.so.p/src_lib_plot.c.o libnotcurses.so.p/src_lib_progbar.c.o libnotcurses.so.p/src_lib_reader.c.o libnotcurses.so.p/src_lib_reel.c.o libnotcurses.so.p/src_lib_render.c.o libnotcurses.so.p/src_lib_selector.c.o libnotcurses.so.p/src_lib_sixel.c.o libnotcurses.so.p/src_lib_sprite.c.o libnotcurses.so.p/src_lib_stats.c.o libnotcurses.so.p/src_lib_tabbed.c.o libnotcurses.so.p/src_lib_termdesc.c.o libnotcurses.so.p/src_lib_tree.c.o libnotcurses.so.p/src_lib_unixsig.c.o libnotcurses.so.p/src_lib_util.c.o libnotcurses.so.p/src_lib_visual.c.o libnotcurses.so.p/src_lib_windows.c.o -Wl,--as-needed -Wl,--no-undefined -fuse-ld=mold -shared -fPIC -Wl,-soname,libnotcurses.so -Wl,--start

it looks like you're trying to compile notcurses in your own way? i don't understand why this is necessary: a meson project can just link against the prebuilt notcurses, no?

mold: error: undefined symbol: pow

this probably needs -lm, but again, why are you trying to compile it using a non-standard means? is cmake unavailable to you? i'm going to close this, but feel free to ask further questions.
