Hi all,
I am experiencing a bad gcc/libgcc dependency cycle on PPC 10.5 which I
do not have on Intel.
I always used with success gcc 4.8 & gcc7.
Upgrade process installed gcc 15 and libgcc15 (took days to compile!).
Now I have this situation:
port installed | grep gcc
gcc7 @7.5.0_4 (active)
gcc10-bootstrap @10.5.0_0+universal (active)
gcc15 @15.2.0_0 (active)
gcc48 @4.8.5_6 (active)
gcc_select @0.1_10 (active)
libgcc @9.0_0
libgcc @15_0 (active)
libgcc6 @6.5.0_4 (active)
libgcc15 @15.2.0_0 (active)
Now if I want to use gcc7 forcing it for ports, like this:
sudo port -v upgrade gobject-introspection configure.compiler=macports-gcc-7
<...>
---> Cleaning libgcc14
---> Removing work directory for libgcc14
Updating dependencies for gcc_select @0.1_10
Updating dependencies for gcc7 @7.5.0_4
---> Installing libgcc13 @13.4.0_1 (2/9)
---> Computing dependencies for libgcc13......
libgcc11 is known to fail. Try to install anyway? [y/N]: y
.
libgcc12 is known to fail. Try to install anyway? [y/N]: y
.
libgcc13 is known to fail. Try to install anyway? [y/N]: y
The following dependencies will be installed:
libgcc10
libgcc11
libgcc12
libgcc13
libgcc7
libgcc8
libgcc9
Continue? [Y/n]:
Error: The following dependencies were not installed because all of them
have unmet dependencies (likely due to a dependency cycle): libgcc7
libgcc8 libgcc9 libgcc10 libgcc11 libgcc12 libgcc13
Error: Problem while installing libgcc13 @13.4.0_1
Error: Follow https://guide.macports.org/#project.tickets if you believe
there is a bug.
on Intel, I got less intermediate libgcc and their installation was also
quick!
If I do:
sudo port -v upgrade gobject-introspection
configure.compiler=macports-gcc-4.8
The following new ports will be installed as dependencies:
libgcc13
libgcc12
libgcc11
libgcc10
libgcc9
libgcc8
libgcc7
Continue? [Y/n]:
and now libgcc13 installation started without warnings that it will
fail. However it starts unpacking full libgcc13 sources so I fear it
will take ages.
