Re: Building GIT on HP-UX: "make test" fails

Hi!

Thanks for that. It seems the basic problem is: fatal: your vsnprintf is broken

However from my own programming I realized that HP-UX and Linux vsnprintf return different values. Here's how I deal with it:

My comment says:
Define ``C99_LIBRARY'' fixes incompatible return value of
 * ``snprintf()'' that causes memory corruption on error with C99-compliant
 * C library. 
[...]
 * Handle negative return value of ``snprintf()'' properly.
[...]
        csp[cap] = '\0';
        d = snprintf(csp, cap, "%s", base);
#ifdef  C99_LIBRARY
        if ( d > cap )
                d = cap;
#else
        if ( d > 0 )
#endif
                csp += d, cap -= d;

Back to the test output; here it is:

Note: moving to 'A' which isn't a local branch
If you want to create a new branch from this checkout, you may do so
(now or later) by using -b with the checkout command again. Example:
  git checkout -b <new_branch_name>
HEAD is now at 0ddfaf1... A
[detached HEAD d9df450] B
 1 files changed, 1 insertions(+), 0 deletions(-)
 create mode 100644 B.t
Previous HEAD position was d9df450... B
