 |
|
Hello,
I want to compile sci-libs/ceres-solver with the the "sparse" USE flag enabled. I set it in package.use but somehow it's not getting picked up at emerge time and doesn't even seem to be recognized as an option by equery:
| Code: |
~ # cat /etc/portage/package.use | grep ceres
sci-libs/ceres-solver doc examples c++11 gflags sparse schur lapack -abi_x86_32
~ # emerge -pv ceres-solver
* IMPORTANT: 5 config files in '/etc/portage' need updating.
* See the CONFIGURATION FILES and CONFIGURATION FILES UPDATE TOOLS
* sections of the emerge man page to learn how to update config files.
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ~] sci-libs/ceres-solver-1.12.0:0/1::gentoo USE="c++11 doc examples gflags lapack openmp schur -cxsparse (-sparse) -test" ABI_X86="(64) -32 (-x32)" 0 KiB
Total: 1 package (1 reinstall), Size of downloads: 0 KiB
~ # equery uses ceres-solver
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for sci-libs/ceres-solver-1.12.0:
U I
- - abi_x86_32 : 32-bit (x86) libraries
+ + c++11 : Build ceres-solver using the C++11 standard
- - cxsparse : Enable simple support for sparse matrix algebra from sci-libs/cxsparse with no LAPACK dependencies
+ + doc : Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
+ + examples : Install examples, usually source code
+ + gflags : Use dev-cpp/gflags for flag parsing
+ + lapack : Add support for the virtual/lapack numerical library
+ + openmp : Build support for the OpenMP (support parallel computing), requires >=sys-devel/gcc-4.2 built with USE="openmp"
+ + schur : Enable fixed-size schur specializations (disable if binary size is an issue)
- - test : Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be
toggled independently)
|
Am I just missing something stupid here?
Many thanks!
-Justin

Use flag in parentheses means that are masked you can unmask using /etc/portage/profile/package.use.mask, but if masked there is a reason
| /usr/portage/profiles/base/package.use.mask: | # Pacho Ramos <pacho@gentoo.org> (11 Nov 2018)
# sci-libs/spqr is going to be removed
dev-cpp/eigen test
kde-apps/cantor julia
sci-libs/ceres-solver sparse |

Thanks so much!
Is there a good place for me to learn about the reason for masking it? |

Yes I reported the reason in my previous post (see file /usr/portage/profiles/base/package.use.mask)

| Many thanks fedeliallalinea! I see that there is a note that sci-libs/spqr will be removed. Do we know why it will be removed? |
