GDAL build for Solaris sparcv9 fails after libraries successfully built

Bradford,

I don't have access to SunOS on Sparc but only Solaris Express Dev. Edition what's not very helpful here. Anyway, I will try to give some suggestion.

First, you don't need to add -mcpu and -m64 flags to all *FLAGS manually. You can just use USER_DEFS and GDAL makefiles will append it automatically where required:

• for .c files compiled as C programs (like gdalinfo.c, gdaltindex.c) to CFLAGS
• for .cpp files compiled as C++ programs (like ogrinfo.cpp, ogr2ogr.cpp), to CXXFLAGS

Note, these options are not needed to be added to CPPFLAGS.

Could you try to pass your flags as follows and let me know if it works?

make 'USER_DEFS='"-mcpu=v9 -m64"

then you should see these flag appended automatically, like this:

gcc -Wall -Wdeclaration-after-statement -fPIC -O2  -mcpu=v9 -m64
...

Bradford,

I'd like to give a few additional notes. I'm not sure what's the version of GCC and binutils on your SunOS but there have been some changes in GCC regarding flags like -march and -mcpu. These two flags are considered as old style and are not supported in new versions of GCC+binutils (you may get errors like error: invalid option cpu):

• GCC 3.2.x and binutils 2.13 support old style flags
• GCC 3.3.x and binutils 2.14 (and later versions) support new flags

The new flag I'm referring here is -mtune and if you have newer GCC you probably will need to use -mtune=v9. For details, I'd suggest to run man gcc and check -march, -mcpu and -mtune flags info. In example, manual for GCC 4.0.x says:

    -mcpu=cpu-type
           A deprecated synonym for -mtune.

BTW, there is another way to specify these flags, next to use USER_DEFS:

export CFLAGS="-mcpu=v9 -m64"
export CXXFLAGS=$CFLAGS
./configure
make
...

In this version, you should see your flags used in the ./configure summary.

Here is more information about changes related to -mcpu/-mtune flags:

During more detailed investigation we've identified there are some issues like ignored CXXFLAGS and CFLAGS in GDALmake.opt.in file for debug building, etc. So, new reports was created dedicated to discussion about similar issues:

1929 - Missing compilation and linking flags on Unix

According to the #1929, the problem is with not properly used LDFLAGS. However, it's too risky to fix it in stable branch 1.4, so I'm moving this ticket to 1.5.0 and then we will apply fixes only in trunk.

Fixed setting user's CFLAGS and CXXFLAGS (r13129)

Hopefully, this issue has been fixed by patches applied to this ticket (see changeset numbers in comments above) as well as patches applied for #1929.
