README_LINUX.txt for PortMidi
|
|
Roger Dannenberg

29 Aug 2006
|
|
|
|
To make PortMidi and PortTime, go back up to the portmidi
|
|
directory and type
|
|
|
|
make -f pm_linux/Makefile
|
|
|
|
(You can also copy pm_linux/Makefile to the portmidi
|
|
directory and just type "make".)
|
|
|
|
The Makefile will build all test programs and the portmidi
|
|
library. You may want to modify the Makefile to remove the
|
|
PM_CHECK_ERRORS definition. For experimental software,
|
|
especially programs running from the command line, we
|
|
recommend using PM_CHECK_ERRORS -- it will terminate your
|
|
program and print a helpful message if any PortMidi
|
|
function returns an error code.
|
|
|
|
If you do not compile with PM_CHECK_ERRORS, you should
|
|
check for errors yourself.
|
|
|
|
This code has not been carefully tested; however,
|
|
all test programs in pm_test seem to run properly.
|
|
|
|
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".
