I'm trying to append the contents of one archive file to another. AR will add the two archives, but not update the symbol table of the receiving archive.
Eg:
% ar -rs big.a file1.o file2.o small.a <snip>
As a workaround, I've changed my code to: cp small.a big.a ar -rs big.a file1.o file2.o
This works, but obviously is not a general solution.
Any suggestions?
Yes. Extract the members of all source archives (eg. using "ar x") and add them to the target archive. The ar program isn't very smart about what it allows you to add to an archive. On some platforms, such as AIX, you purposely add both binary and non-binary data to an archive to produce a distributable package. You can see an example of archive extraction and here: http://cvs.openwbem.org/cgi-bin/viewcvs.cgi/openwbem/ow_ar.sh?rev=1.5&conten... This ow_ar.sh script acts as a wrapper around ar, which expects the path to the ar program and any "unusual" parameters as the first arguments followed by a '--'. It will extract the objects from each source archive provided thereafter, rename them so they don't collide with each other, and create the target archive. Example usage (to clarify my horrible description): ow_ar.sh /usr/bin/ar -- cru TARGET.a source1.o source2.o SOURCE3.a ... This will create TARGET.a with the object files from SOURCE3.a and all of the other objects specified on the command line, while avoiding object file name collision. I hope that helps. -Kevin- _______________________________________________ Do not post admin requests to the list. They will be ignored.
