#53 need to rebuild on Linux64 with older GLIBC

[Lee Moore]

I am generally very happy with the functionality of this tool - great job.

However I have a requirement to run the packaged executable on an older Centos 5.7 system, which only supports an older GLIBC.
So after creating the executable there is a dependency on a newer GLIBC

I tried to build freewrap from source on the Centos5.7 machine
I successfully built tcl/tk-8.6.2 and also built zip30 from info-zip @ sourcforge,
but when I attempt to run make in the linux64 directory I get the following error

linux64/../generic/zipmain.c:244: error: 'path_prefix undeclared (first use in this functions)

I grepped through all of the source, and can only find a reference to 'path_prefix' in this file itself, so I am totally confused.

Could I make a request to build freewrap with an earlier GLIBC dependancy, or provide some more details about how to rebuild from source

Many thx

Actually one further thought on this issue.

I am guessing if you make all the libraries available, all I would need to do is relink the executables on the target machine, it would then use the GLIBC version for that machine.
I see that only the archive libraries are referenced, therefore there should be no dependancy on the version of GLIBC I think

Thx

It doesn't look like this works. When I tried this, the object modules required the same GLIBC that they were compiled against.

I installed Centos 5.11 (DVD ISOs of 5.7 don't seem to be available) and compiled freeWrap 6.63 using the TCL/TK 8.6.2 sources.

I successfully built freeWrap using the build instructions in the freeWrap documentation. I did need to take a minor detour to add a few symbolic links in the /usr/lib64 directory. The symbolic links for the X11 libraries were a bit non-standard under Centos 5.11.

I did not encounter the error message you mentioned above. However, I used the zip31c package, as required by the build documentation, while you used zip30. You must use zip31c in order to be successful.

Hi Dennis

Thanks for the info.
I think the root cause of my issues is that I expected to find the build instructions in the source directory, I didnt think to look in the freewrap.pdf. So I started to deconstruct the Makefile to try to work out what it was expecting to see installed as its pre-requisites :-(

Following the pdf instructions I managed to rebuild from source, I ommitted some of the additional packages such as sqlite, and the associated TCL DB packages, these are not required for my application.

I have tested on my target system, and now the wrapped executable only requests GLIBC_2.5, which is exactly what I wanted - perfect !

Many Thx
