README_LINUX.txt for PortMidi

Contents:
To make PortMidi
The pmdefaults program

A note about amd64
Using autoconf
Using configure
Changelog
See ../README.md for general instructions.
THE pmdefaults PROGRAM
(This may be obsolete. It is older than `../README.md` which
also discusses pmdefaults, and Java support may be removed
unless someone claims they use it... -RBD)
You should install pmdefaults. It provides a graphical interface
for selecting default MIDI IN and OUT devices so that you don't
have to build device selection interfaces into all your programs
and so users have a single place to set a preference.
Follow the instructions above to run ccmake, making sure that
CMAKE_BUILD_TYPE is Release. Run make as described above. Then:
sudo make install
This will install PortMidi libraries and the pmdefault program.
You must alos have the environment variable LD_LIBRARY_PATH set
to include /usr/local/lib (where libpmjni.so is installed).
Now, you can run pmdefault.
SETTING LD_LIBRARY_PATH
pmdefaults will not work unless LD_LIBRARY_PATH includes a
directory (normally /usr/local/lib) containing libpmjni.so,
installed as described above.
To set LD_LIBRARY_PATH, you might want to add this to your
~/.profile (if you use the bash shell):
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH
A NOTE ABOUT AMD64:
When compiling portmidi under linux on an AMD64, I had to add the -fPIC
flag to the gcc flags.
Reason: when trying to build John Harrison's pyPortMidi gcc bailed out
with this error:
./linux/libportmidi.a(pmlinux.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC
./linux/libportmidi.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
error: command 'gcc' failed with exit status 1
What they said:
http://www.gentoo.org/proj/en/base/amd64/howtos/index.xml?part=1&chap=3
On certain architectures (AMD64 amongst them), shared libraries *must*
be "PIC-enabled".
