| I was getting this error within compiling the net-print/hpoj within gentoo. cc -O -Wall -g -I/var/tmp/portage/hpoj-0.91-r3/work/hpoj-0.91/include -L/var/tmp/portage/hpoj-0.91-r3/work/hpoj-0.91/lib/hpojip -L/var/tmp/portage/hpoj-0.91-r3/work/hpoj-0.91/lib/ptal -L/var/tmp/portage/hpoj-0.91-r3/work/hpoj-0.91/lib/sane -DHPOJIP_INTERNAL -fPIC -c -o xjpg_fix.shared.o xjpg_fix.c xjpg_fix.c: In function 'jpgFix_getActualTraits': xjpg_fix.c:512: error: invalid lvalue in assignment xjpg_fix.c:533: error: invalid lvalue in assignment xjpg_fix.c:549: error: invalid lvalue in assignment xjpg_fix.c:560: error: invalid lvalue in assignment xjpg_fix.c:581: error: invalid lvalue in assignment xjpg_fix.c:587: error: invalid lvalue in assignment xjpg_fix.c:595: error: invalid lvalue in assignment xjpg_fix.c:605: error: invalid lvalue in assignment xjpg_fix.c:610: error: invalid lvalue in assignment make[1]: *** [xjpg_fix.shared.o] Error 1 make[1]: Leaving directory `/var/tmp/portage/hpoj-0.91-r3/work/hpoj-0.91/lib/hpojip' make: *** [just_compile] Error 2 !!! ERROR: net-print/hpoj-0.91-r3 failed. Call stack: ebuild.sh, line 1546: Called dyn_compile ebuild.sh, line 937: Called src_compile hpoj-0.91-r3.ebuild, line 47: Called die !!! compilation failed !!! If you need support, post the topmost build error, and the call stack if relevant. Found a patch on the web that required altering the file hpoj/lib/hpojip/xjpg_fix.c with this fix. -#define MYLOCATE(p) (void *)(p)=(g->headerBuffer+lenAddedHeader) +#define MYLOCATE(p) p=(g->headerBuffer+lenAddedHeader) I am using the kernel 2.6.17-gentoo-r8 as well, with gcc versoin 4.1.1. So proceeded to create a ebuild for this to get the patch into the gentoo system, basically if you create a directory /usr/local/portage/net-print/hpoj by mkdir -p /usr/local/portage/net-print/hpoj the -p will create the hierarchy if not present. And also alter the /etc/make.conf to include the portage overlay (basically adding in you own versions of the software ebuild structure). PORTDIR_OVERLAY="/usr/local/portage/" If you copy the files from the attached zip file (you will need to login to get the files) and then ebuild /usr/local/portage/net-print/hpoj/hpoj-0.91-r4.ebuild digest just to make sure, but this will create the Manifest of the ebuild, this should be correct within the zip file, but on the safe side. Then to install the software emerge hpoj this will now update to the version that is present within within the overlay of portage, e.g. The one that you just created, I called this a version -r4 instead of the -r3 because it is a fix to the -r3 version. Well anyway, hope that is helps people. |
