Hi,

I installed git 2.1.3 on sparc 8 by source code with make install, however I got git core dump during 'git clone'.

I used command as below to compile and install:

./configure --prefix=/usr/local/git-2.1.3/ --enable-pthreads sudo gmake NO_GETTEXT=1 install

Below I pasted the gdb bt full details, does anyone have any idea why this happened?

Thanks very much! Victor

We tried to start a thread in start_async, but it failed. We then pass the error number to strerror(), and try to print the result. That seems to involve feeding garbage to vsnprintf, so presumably what strerror() handed us back was garbage.

Are you sure that pthreads really work on your platform? Between the thread failure and the garbage strerror(), it sounds like there might be some weird linking problems. Does running "./configure --disable-pthreads" produce a working build?

Re: Installed git 2.1.3 on sparc 8, but got core dump during 'git clone'

Hi,

Thanks for the input. With below command, I got new error as below:

./configure --prefix=/usr/local/git-2.1.3/ --disable-pthreads sudo gmake NO_GETTEXT=1 install

Undefined                       first referenced

type_cas_lock                       builtin/index-pack.o
ld: fatal: Symbol referencing errors. No output written to git

How can I overcome this?

Thanks, Victor

The NO_PTHREADS build was broken in v2.1.2 and v2.1.3. The fix, from commit e0e2128 (index-pack: fix compilation with NO_PTHREADS, 2014-10-11) is in the current "master" branch. If you want to apply it manually, it is just:

diff --git a/builtin/index-pack.c b/builtin/index-pack.c

Re: Installed git 2.1.3 on sparc 8, but got core dump during 'git clone'

Hi Jeff,

Thanks for your help, as your suggestion, I can compile/install git with --disable_ptheads now.

While ran 'git clone', it still got core dump.

Would you please have a look at it?

It seems as if your Git still wants to create a pthread, Did you use --disable-pthreads or --disable_ptheads ?

Re: Installed git 2.1.3 on sparc 8, but got core dump during 'git clone'

Hi,

I used below command to configure: ./configure --prefix=/usr/local/git-2.1.3/ --disable-pthreads

Actually, I think the error message is quite clear this time, it is about hook of "Deleting a tag is not allowed in this repository".

Can I try to disable the hook?

Thanks, Victor

Re: Installed git 2.1.3 on sparc 8, but got core dump during 'git clone'

Hi,

I tried to install this version git on sparc 10, the git clone command can be executed successfully.

So is there any specific issue about sparc 8 for git to make/install?

Anyway, I will try to install on sparc 8 again.

Thanks, Victor
