Make error line 479: LINK problem: d:/mat/kderoot/devel/inkscape-devel/mingw/bin/../lib/gcc/mingw32/4.5.0/../../../../mingw32/bin/ld.exe: cannot find -lgomp

( detail is in attachment )

I cannot fount -lgomp, I wounder whether there is something missing?

My platform is:
os => windows7, 32-bits
rev=> 9702, from trunk
reproduce step => http://wiki.inkscape.org/wiki/index.php/Win32Port

hope these infomation helps.

A small BAT script is also attached for convenient use, wish it helps...

see also <http://thread.gmane.org/gmane.comp.graphics.inkscape.devel/34669>

Two proposed solutions:
a) «Just have to select OpenMP Support when installing TDM-GCC to fix this»
b) «Apparently the location of libgomp has been changed in 4.5, so I moved it to the old location (lib/gcc/mingw32/bin), as I figured changing the location in the build files would probably break older versions.»

[su_v (suv-lp)]

Changing status to 'Confirmed' because the same issue was reported and confirmed for GCC 4.5 in inkscape-devel.

[Mat (matlinuxer2)]

Verified.
The solution referred in mailling-list works. And rev=9072 pass build and launch program successfully.
Many thanks!
