    Post make won't filter-out

    Trying to get this to filter out 2 files so they don't confuse my linker into thinking my project failed to compile when these 2 are the ONLY 2 causing the errors when they're not even supposed to be in the list
    Code:
    SRC_LUA:=$(wildcard $(SRC_LUA_DIR)/*.c)
SRC_LUA:=$(filter-out $(LUA_SRC_DIR)/lua.c,$(SRC_LUA))
SRC_LUA:=$(filter-out $(LUA_SRC_DIR)/luac.c,$(SRC_LUA))
    Any help fixing this is appreciated

    SRC_LUA_DIR is not the same as LUA_SRC_DIR !

    New problem, tried installing various math libraries but still getting this output:

    The lua stuff should compile fine once the right math library is installed but I can't figure out which one, any ideas?

    You need to add '-lm' to the end of your link command line.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Deleting the object files probably isn't necessary.
    Did you add the -lm (note that's a lowercase L, not the digit 1) at the very end of the line?
    Post the line.

    I believe both Salem and myself said to put it at the END OF THE LINE.
    And it's only needed on the linking line (the very last one).
    Maybe give that a try.

    I reaally didn't expec it to make a difference but I tried and wowee did those errors disappear fast, any suggestions for that tmpnam() one that doesn't involve turning off -Werror, I'm the kind that likes to treat poor programming as hacking that needs to be replaced

    It is a little odd that the positioning of the -lm makes a difference. On some systems it doesn't matter.

    For a tmpnam() replacement you might try one of these:
    tmpfile, tmpfile_s - cppreference.com
    mkdtemp (see mkstemp on the same page)

    any suggestions for that tmpnam()
    What's wrong with the option provided by the warning message (better use `mkstemp')?

    Haven't looked yet, was reading something that updated with 3 chapters instead of one, meaning the rss link would show as read causing me to not realise about it after I close it and go to sleep (not sleeping now btw), I figured I'd get suggestions while I'm doing that and save me waiting for it later if I do need 'em

    Edit: returns an open handle, needs to be a string to push into lua, useful for redirecting command string output into a readable file, in the case of my app it is essential for ensuring such output gets directed to stdout fo whatever text editor/ide or shell/batch calls it

    For a tmpnam() replacement you might try one of these:
    tmpfile, tmpfile_s - cppreference.com
    mkdtemp (see mkstemp on the same page)
    thx, I'll take a look soon

    Sadly, it's not standard C and it returns a file descriptor (int) instead of a FILE*. Not that that's a big problem, of course (just use fdopen to get a FILE*). If you need the filename then it's the only option. If you don't actually need the filename but just the temporary file, then tmpfile is standard and probably better for the task.
