Problems linking OpenSees with Scientific Linux 4.1

[kryan]

Hi,

I have just tried to build OpenSees on Scientific Linux 4.1 (functionally equivalent to Redhat Enterprise Linux 4). I get errors of the following type while linking. OpenSSL is installed on the machine so the libraries should be there. Any suggestions?

it's not enough that they are on thye machine .. you have to tell the linker to include those ssl libraries .. you need to add some lines to the Makefile.def ..

MACHINE_LINKLIBS

or MACHINE_SPECIFIC_LIBS

[kryan]

Of course. Near as I can tell, the ssl library files are located in /lib and/or /usr/lib on my machine,

and are referenced in makefile.def as:

MACHINE_LINKLIBS = -L$(BASE)/lib

where BASE is the root directory, and

MACHINE_SPECIFIC_LIBS = -ldl -lieee -lm -lc -lg2c -Wl,-rpath,/usr/lib \
/usr/lib/mysql/libmysqlclient.a

Any thoughts?

Meanwhile, I have successfully linked by removing -D_MYSQL from C++ flags. Presumably this is no problem as long as I don't try to use the database command?

your libmysqlclient needs more libraries .. suggest you fgrep around your lib directories to see where SSL_write is actually defined.
