Hello, We have encountered what looks like a bug while building Xrootd that seems to be triggered by having a long git tag. Here is a build log snippet: Building CXX object src/CMakeFiles/XrdFileCache.dir/XrdFileCache/XrdFileCacheFactory.cc.o [ 97%] [ 97%] [ 97%] [ 97%] Building CXX object src/CMakeFiles/XrdFileCache.dir/XrdFileCache/XrdFileCacheIOEntireFile.cc.o Building CXX object src/CMakeFiles/XrdFileCache.dir/XrdFileCache/XrdFileCacheIOFileBlock.cc.o Building CXX object src/CMakeFiles/XrdFileCache.dir/XrdFileCache/XrdFileCachePrefetch.cc.o Building CXX object src/CMakeFiles/XrdFileCache.dir/XrdFileCache/XrdFileCacheInfo.cc.o Linking CXX executable xrdadler32 Linking CXX shared library libXrdPosixPreload.so Linking CXX shared library libXrdSecgsi.so [ 97%] Built target XrdPosixPreload [ 97%] Built target xrdadler32 [ 97%] Built target XrdSecgsi Linking CXX executable xrdfs Scanning dependencies of target XrdSecgsiGMAPDN [ 97%] Building CXX object src/CMakeFiles/XrdSecgsiGMAPDN.dir/XrdSecgsi/XrdSecgsiGMAPFunDN.cc.o Linking CXX shared library libXrdFfs.so /lsst/home/lsstsw/build/xrootd/src/XrdFileCache/XrdFileCacheFactory.cc:49: error: initializer-string for array of chars is too long [ 97%] Built target xrdfs [ 97%] Built target XrdFfs make[2]: *** [src/CMakeFiles/XrdFileCache.dir/XrdFileCache/XrdFileCacheFactory.cc.o] Error 1 make[2]: *** Waiting for unfinished jobs.... The tag we are using is: 4.0.0rc3-qsClient2.lsst1 , which is 24 characters. XrdFileCacheFactory.cc:49 has a line that uses the XrdVERSIONINFO macro, which apparently joins strings together based on a discovered git tag. It's interesting that the length limit was only hit when compiling XrdFileCacheFactory.cc -- I'm sure the macro was referenced in many parts of code that successfully compiled. Ideally, I think the code should be robust enough to handle arbitrarily-long tags. But realistically, I think a warning and some creative tag shortening: "SomebodysReallyReallyLongTag" --> "SomebodysRe...gTag" would suffice, and be simpler to implement. I'm not positive that the issue exists on the mainline xrootd--if there have been updates to the tag/version handling, I should certainly pull a new version. The version I'm using is in my repository on github: wangd/xrootd, tag: qsClient2 (but re-tagged to the long string above).
