We have compiled subversion 1.10.2 on AiX machine using the compile command :-
./configure CFLAGS="-I/temp1110/subversion/zlib" --without-berkeley-db --with-apr=/temp1110/subversion/apr --with-apr-util=/temp1110/subversion/apr-util --with-lz4=internal --with-utf8proc=internal --disable-nls
Whereas, after generating the required files using "make" command. We are unable to create a repository. After passing the command ./svnadmin create /temp1110/home/Repo_test", we get the error:
svnadmin: E000009: Can't write '/temp1110/home/Repo_test/db/current'
atomically svnadmin: E000009: Can't flush file
'/temp1110/home/Repo_test/db' to disk: Bad file number
Any idea how to resolve this?
Well, you cannot solve this, this is a bug in subversion.
Or rather an AIX-specific problem: fsync(2) called on a directory returns errno=EBADF which makes subverions/libsvn_subr/io.c:svn_io_flush_to_disk sad.
This can be fixed with the following patch:
