I have been trying to install Gimp-gap on an iMac (2GHz Intel Core 2 Duo, 1GB RAM) fairly unsuccessfully! I originally installed Xcode tools from the OS X 10.4 CD but went back and downloaded v2.5 from Apple, removed Macports and re-installed 1.52 including selfupdate. I was able to install and run Gimp 2.4 but Gimp-gap has consistently failed compiling msmpeg4. Anyone else come across this or know what is wrong? Here's the listing with the error. ---- snip ----- ---> Fetching gimp2 ---> Attempting to fetch gimp-2.4.1.tar.bz2 from http://gimp.mirrors.hoobly.com/gimp/v2.4/ ---> Verifying checksum(s) for gimp2 ---> Extracting gimp2 ---> Configuring gimp2 ---> Building gimp2 with target all ---> Staging gimp2 into destroot ---> Installing gimp2 2.4.1_0 ---> Activating gimp2 2.4.1_0 ---> Cleaning gimp2 ---> Fetching gimp-gap ---> Attempting to fetch gimp-gap-2.2.2.tar.bz2 from ftp://ftp.gimp.org/pub/gimp/plug-ins/v2.2/gap/ ---> Verifying checksum(s) for gimp-gap ---> Extracting gimp-gap ---> Configuring gimp-gap ---> Building gimp-gap with target all Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_graphics_gimp-gap/work/gimp-gap-2.2.2" && make all " returned error 2 Command output: gcc -O3 -g -Wall -Wno-switch -O2 -no-cpp-precomp -DHAVE_LRINTF -fno-common -pipe -fomit-frame-pointer -DHAVE_AV_CONFIG_H -I.. -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE -c -o h263.o h263.c In file included from h263.c:40: mpeg4data.h:226: warning: pointer targets in initialization differ in signedness mpeg4data.h:227: warning: pointer targets in initialization differ in signedness mpeg4data.h:330: warning: pointer targets in initialization differ in signedness mpeg4data.h:331: warning: pointer targets in initialization differ in signedness h263.c: In function 'h263_pred_dc': h263.c:1522: warning: pointer targets in assignment differ in signedness h263.c: In function 'mpeg4_encode_vol_header': h263.c:2374: warning: pointer targets in passing argument 2 of 'ff_write_quant_matrix' differ in signedness h263.c:2375: warning: pointer targets in passing argument 2 of 'ff_write_quant_matrix' differ in signedness h263.c: In function 'ff_mpeg4_pred_dc': h263.c:2503: warning: pointer targets in assignment differ in signedness gcc -O3 -g -Wall -Wno-switch -O2 -no-cpp-precomp -DHAVE_LRINTF -fno-common -pipe -fomit-frame-pointer -DHAVE_AV_CONFIG_H -I.. -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE -c -o h261.o h261.c gcc -O3 -g -Wall -Wno-switch -O2 -no-cpp-precomp -DHAVE_LRINTF -fno-common -pipe -fomit-frame-pointer -DHAVE_AV_CONFIG_H -I.. -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE -c -o msmpeg4.o msmpeg4.c msmpeg4.c: In function 'msmpeg4_pred_dc': msmpeg4.c:838: warning: pointer targets in assignment differ in signedness msmpeg4.c: In function 'msmpeg4_encode_block': msmpeg4.c:727: error: can't find a register in class 'BREG' while reloading 'asm' {standard input}:15149:non-relocatable subtraction expression, "_msmpeg4v34_decode_mb" minus "L00000000003$pb" {standard input}:15149:symbol: "_msmpeg4v34_decode_mb" can't be undefined in a subtraction expression {standard input}:15132:non-relocatable subtraction expression, "_msmpeg4v12_decode_mb" minus "L00000000003$pb" {standard input}:15132:symbol: "_msmpeg4v12_decode_mb" can't be undefined in a subtraction expression {standard input}:15114:non-relocatable subtraction expression, "_wmv2_decode_mb" minus "L00000000003$pb" {standard input}:15114:symbol: "_wmv2_decode_mb" can't be undefined in a subtraction expression make[4]: *** [msmpeg4.o] Error 1 make[3]: *** [lib] Error 2 make[2]: *** [/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_graphics_gimp-gap/work/gimp-gap-2.2.2/extern_libs/ffmpeg/libavformat/libavformat.a] Error 2 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 Error: Status 1 encountered during processing. sk8-mac:~ sk8r$
