Build libmcrypt Fails

tronayne · 03-29-2008, 11:32 AM

Hi.

I'm trying to build libmcrypt-2.5.8.tar.bz2 using src2pkg -D -DEST -p=/usr/local -e='--enable-dynamic-loading --disable-posix-threads' -C libmcrypt-2.5.8.tar.bz2; it fails with a configure error (if I configure manually with the above arguments it configures and builds just fine).

I assume I'm doing something wrong -- any hints?

Thanks.

The message is:

Code:

This usually happens because of missing libraries, or you
may need to pass extra options to configure using EXTRA_CONFIGS.
Found an RPM .spec file which shows this:
Requires: libmcrypt = %{version}

Sorry I hadn't noticed your post till today.
When you configure manually does the routine end with some sort of oupuit message or prompt? Someitmes these text-output messages confuse the error handling.
In the worst case, you could substitute a line or two of manual code to replace the regular src2pkg functions -something like this:

# configure_source
# compile_source
# fake_install

cd $SRC_DIR ;
./configure --prefix=/usr/local --enable-dynamic-loading --disable-posix-threads
make
make DESTDIR=$PKG_DIR install

It may be that I have changed some code which would fix this in the next version which will be released soon. But, the above fix is a good one to know anyway as it is still sometimes needed -at least for some sources.
You can generate a starting script with:

src2pkg -N libmcrypt-2.5.8.tar.bz2

The just do the edit as shown(you don't need to bother with the EXTRA_CONFIGS, etc since you will code that manually anyway).

Then, run it with this:
src2pkg -X -D -C

Hope this fixes it for you in the short term. I'll have a look at the sources in question to see what is happening.

Thanks for responding.

When I configure manually, it completes successfully, I can compile successfully (and install, but I didn't want to do that).

I'll fiddle with the above and see if I can get a package made that way.

Thanks again.

Okay, I just checked this problem out. Configuration fails because libltdl thinks we are trying to specify two different architectures when we export bot CFLAGS and CXXFLAGS.
You can fix this in the src2pkg files by opening the file /usr/libexec/src2pkg/06-configure_source and commenting out the two lines with this:
export CXXFLAGS=$FLAG_LINE

Just change them to:
#export CXXFLAGS=$FLAG_LINE

You'll find them both around line 290 of the file. Thanks for steering me to this error -it's a strange and unlikely one -the export of CXXFLAGS is a recent addition and not something I'd expect to see problems with. Nor have I run across it among my many compiles, so I'm glad you reported it. Once you've made that change you should have no trouble using the command you were trying originally.

Ah-Ha!

That took care of that... now, it's on to rebuilding PHP with mcrypt and all will be well that ends.

Thanks
