Error Linking with IUP toolkit
Hi,
Been trying to compile a simple C program using the open source IUP toolkit provided by Tecgraf (makers of Lua). Keep getting the error below:
Based on the documentation the following libraries are dependancies:
iupwin* -> gdi32 user32 comdlg32 comctl32 ole32 (system - Windows)
button.o is a sample program provided in the IUP distribution
Code:
c:\dev\IUP>make
gcc -L C:\dev\IUP\libs -o main.exe button.o libiup.a libiupcd.a libiupim.a -lgdi32 -luser32 -lcomdlg32 -lcomctl32 -lole32

Can anyone see the issue here...
