Compile error

[Mike]

Hi,

So I exported from the svn repository and did ./buildgpl and I get the
following erro message

k_error
cc1: warnings being treated as errors
gplsrc/k_error.c: In function ‘k_error’:
gplsrc/k_error.c:246: error: format not a string literal and no format
arguments

This is on ubuntu 9.10

Is this expected?

Regards
Mike

Good for you! I can't get this step to work for me. Undoubtedly
because I don't know what I'm doing with svn. How did you make it
work?

and did ./buildgpl and I get the

Edit the buildgpl script, and remove -Werror from the QM_GCC_OPTIONS
line, and try again. If that don't work, try adding -Wno-packed. If
that don't work , try adding -Wno-pointer-sign.

svn is easy..... - I must presume that you have "apt-get install
subversion" first

"svn export http://whatever qmsys"
will export the repository at the point you make and create a
directory qmsys

Alternatively,
"svn co http://whatever qmsys"
will check out the repository to a working copy named qmsys where
every directory will have a .svn control directory and you can commit
and update from your working copy.

No, that did not appear to be the issue, so I check line 246 in the c-
code - OMG that is scary. I changed the line which read "sprintf(s +
n, sysmsg(1120));" to "sprintf(s + n, sysmsg(1120),"none");" and the
error message est disparu. It looked like sprintf required 3 arguments
- whatever sprintf might be....

Thanks for the pointers. Perhaps I'll make an update to the wiki to
clarify things.

I've taken a look at the version of k_error.c in QM2.6-6, and it seems
identical (according to diff). So the error messages looks to be
something uncovered by a change in the compiler/OS/libraries/etc.

I'll look further...

Well, I finally managed to get free of the snow and out to the server room.

It looks like a change in gcc (or libraries). The Scarlet trunk
snapshot works fine with Ubunto 8.4.3, but produces the error with
Ubuntu 9.10.

Ubunto 9.10 uses gcc 4.4.1, whereas 8.4 uses gcc 4.2.4. Perhaps
there's an appropriate option for gcc, which uses the old behaviour.
Or it might be better to change the code so it compiles cleanly with
either gcc version.

So, if you remove the -Werror option in the buildgpl script, it
compiles whilst warning about the k_error.c file.

I really don't know my way around gcc, so can somebody else comment.
