Fedora Core 4 Install 🔗 link

All,

 
I'm getting the following warnings on an install of Hobbit onto Fedora Core 4, and wanted to find out if they are safe to ignore.

I believe you can safely ignore those. Adding "-funsigned-char" to the
compile-time options will probably eliminate them completely.

I'll do a test-install of FC4 to see if I can weed out those sometime.

for just ordinary names does have some advantages - one of them being
that I always assume chars to be unsigned. "-'q' ? You gotta be joking...")

Where would I pass this at?  Not a programmer, poked around a little on google for it, and tried setting it in CFLAGS, but I still got the warning.  Hobbit does indeed appear to work fine.  It was just a curiosity.

My guess was to add it in the top-level Makefile, near the bottom where
it says

    # Add local CFLAGS etc. settings here
    CFLAGS += -funsigned-char

The Red Hat servers were busy when I tried picking up FC4 the other day,
will try one of the mirrors later.

Oh, do report these kinds of things. Sometimes compiler really do catch 
errors I've made, and I always prefer the compile-phase to go "clean"
without any warnings. Most people - myself included - do feel better
about installing software that compiles without blasting tons of
warnings across the screen.

Henrik,
If you like to get such informations, here is a short example, current source version 4.0.4

Compiler:
cc:   Compaq C V6.5-011 on Compaq Tru64 UNIX V5.1B (Rev. 2650)
cxx:  Compaq C V6.5-011 on Compaq Tru64 UNIX V5.1B (Rev. 2650)

cc: Warning: ../lib/sendmsg.c, line 316: In this statement, the referenced type of the pointer value "&connressize" is "unsigned long", which is not compatible with "int". (ptrmismatch)
cc: Warning: contest.c, line 947: In this statement, the referenced type of the pointer value "&connressize" is "unsigned long", which is not compatible with "int". (ptrmismatch)

$ grep "cc: Warning" setup.log
cc: Warning: digest.c, line 101: In this statement, the referenced type of the pointer value "&md_len" is "int", which is not compatible with "unsigned int" because they differ by signed/unsigned attribute. (ptrmismatch1)
cc: Warning: encoding.c, line 31: In this statement, the referenced type of the pointer value "buf" is "unsigned char", which is not compatible with "const char" because they differ by signed/unsigned attribute. (ptrmismatch1)
.
.
about 300 ptrmismatch1 warnings more, I can send you the whole input if you like a long mail :-)
