I had downloaded the latest qce-ga
qce-ga-0.40d.tar.gz; when I try to make
On RH8 (after moving it to under /usr/src)
I get many errors:
many of them are :
dereferencing pointer to incomplete type
starting in quickcam.c:905 amd much more of the same type in this module)
The last three lines of the log of make are:
quickcam.c: At top level:
quickcam.c:2346: storage size of `quickcam_driver' isn't known
quickcam.c:2116: storage size of `quickcam_template' isn't known
make: *** [quickcam.o] Error 1

Does anybody know what can it be ?

dereferencing pointer to incomplete type
