Howdy Brahmsers.
On my system I've configured ROOT with the following:
./configure linuxegcs --prefix=/usr/local
--with-mysql-libdir=/usr/lib/mysql --with-mysql-incdir=/usr/include/mysql
--enable-soversion --enable-rpath --enable-star.
Testing our DB inteface with bratroot and the following
statements is all fine:
BrMainDb* mainDb = BrMainDb::Instance();
mainDb->SetUserName("query");
mainDb->SetHostName("rcas0005.rcf.bnl.gov");
mainDb->SetDbName("BrahmsMain")
I then try to connect by calling mainDb->Connect() and the error message
is the following:
brat [1] mainDb->Connect()
dlopen error: libmysqlclient.so.10: cannot open shared object file: No such file or directory
Load Error: Failed to load Dynamic link library /usr/local/lib/root/libMySQL.so
Error in <BrMainDb::Connect>: User query couldn't connect to database BrahmsMain @ rcas0005.rcf.bnl.gov
(class TSQLServer*)0x0
*** Interpreter error recovered ***
brat [2]
However, if I add the directory where libmysqlclient.so.10 is situated
into the LD_LIBRARY_PATH environment variable, the everything works fine.
This directory is of course the one specified in the --with-mysql-libdir
flag when configuring root.
Should it be necessary to add the MySQL lib directory to LD_LIBRARY_PATH
(or /etc/ld.so.conf for that matter)? According to you, Christian, in a
mail to the soft list [1] one does not have to add anything to
LD_LIBRARY_PATH to use BRAT2. Is there something that I have missed here?
I know that this has been mentioned on roottalk (e.g. [2], [3]), but as
far as I can see the only work-around there is the use of
LD_LIBRARY_PATH.
Looking forward to some enlightening answer(s).
Best wishes from
Jens Ivar
