Hi, |
| 2 |
|

When I run revdep-rebuild, I get something like the following: |
| 4 |
|
| 5 |
[...] |
| 6 |
* broken /usr/lib/ImageMagick-6.5.2/modules-Q16/coders/avi.la |
| 7 |
(requires /usr/lib/libgomp.la) |
| 8 |
[...] |
| 9 |
* broken /usr/lib/libfftw3l_threads.la (requires /usr/lib/libgomp.la) |
| 10 |
[...] |
| 11 |
|
| 12 |
which in the end wants to emerge as follows: |
| 13 |
|
| 14 |
emerge --oneshot -av media-gfx/imagemagick:0 |
| 15 |
sci-libs/fftw:3.0 |
| 16 |
.......... |
| 17 |
|
| 18 |
These are the packages that would be merged, in order: |
| 19 |
|
| 20 |
Calculating dependencies... done! |
| 21 |
[ebuild R ] media-gfx/imagemagick-6.5.2.9 USE="X bzip2 corefonts |
| 22 |
jpeg openmp perl png svg tiff xml zlib -djvu -doc -fontconfig -fpx |
| 23 |
-graphviz -gs -hdri -jbig -jpeg2k -lcms -nocxx -openexr -q32 -q8 -raw |
| 24 |
-truetype -wmf" 0 kB |
| 25 |
[ebuild R ] sci-libs/fftw-3.2.2 USE="fortran openmp sse sse2 |
| 26 |
(-altivec) -doc -threads" 0 kB |
| 27 |
|
| 28 |
Once this merge completes, re-running revdep-rebuild yields the same results. |
| 29 |
|
| 30 |
It seems that the culprit is /usr/lib/libgomp.la, which is completely |
| 31 |
missing from my system. This is some OpenMP library from GNU[1]. I |
| 32 |
can't find an obvious package in portage which would supply |
| 33 |
libgomp.la. |
| 34 |
|
| 35 |
Both imagemagick and fftw have the openmp use flag turned on. It's not |
| 36 |
switched on in my /etc/portage/package.use so it must come from the |
| 37 |
profile or the ebuild or wherever default USE flags come from. |
| 38 |
|
| 39 |
The fftw ebuild says openmp support is available with gcc >= 4.2, |
| 40 |
while imagemagick says gcc 4.3 is required and has a reference to bug |
| 41 |
#223825[2]. I'm using gcc-4.3.4. |
| 42 |
|
| 43 |
Is there a package that should be installed which provides libgomp.la? |
| 44 |
If there is, shouldn't it be a dependency for imagemagick and fftw? |
| 45 |
And if such a package doesn't exist, what's going on here? How did |
| 46 |
imagemagick and fftw compile in the first place if libgomp.la is not |
| 47 |
available on my system at all? Is anyone else seeing this issue? Do I |
| 48 |
need to file a bug? |
| 49 |
|

Thanks, |
| 51 |
