screwy compiler

[Syntax13]

i was compiling this program and others just fine all day yesterday, but for some reason after i rebooted my computer this morning, gcc sudenly started being screwy. here's what it tells me (and glfw.h and library are where they're supposed to be)


$ gcc -Wall -lglfw -lGL -lGLU -lX11 -lpthread -lm -o LearnGLFW02.exe LearnGLFW02.cpp

anyone have any suggestions of what's wrong?

[rock freak]

the error you are getting is to do with the include libaried everytime its happened with me, any chance of seeign the source code maybe able to give a better answer then :)

(sorry about spelling)

It's clearly a linker problem, as it seems to compile fine. Have you tried passing the path to the libraries? Use the flag -L/path/to/library and see if that works.

[toojays]

Try listing -lglfw last and see if that helps.

[LordHunter317]

You should always list libraries to link last, after the code you wish to compile/link. You should also always list them after search directives.

thank you all for replying, but the problem has been resolved. for some reason i have to write the linking after the file....it's strange because it wask working perfectly fine the other way originally (i saved the exact line into a text file after i got it working on the first day...and after i rebooted, that exact same line didn't work anymore *shrugs*). again, thank you for your replies.
