[Libunwind-devel] Unable to build libunwind on HPIA64

[Ruiz, Carlos M]

Hi

I am trying to build libunwind 1.2.1 on HPIA64, and I got errors because the file mk_Gcursor_i.c seems missing from the src/ia64 subdirectory. I tried 1.3, and the same. Then I tried 1.2, and the error I get now is different. The file mk_Gcursor_i.c is not missing, but I get compilation errors:

The OS is:

Any idea what I can be doing wrong ?
