Hi,
I'm trying to compile some software for OSX, that was developed on
linux (tarball available at http://microarray.org/data/download/
g2c-1.0.tar.gz), and ran into a number of problems, some of which
I solved (or appeared to solve), but I'm now stuck. Any help
would be greatly appreciated. The problems I encountered thus far
were:
1. The first problem is when it tries to compile dust.c:
ccsr-2255b-g5 1002 % make all
compiling g2c.c
compiling g2clib.c
compiling gopt.c
compiling blast.c
compiling complementation.c
compiling complexity.c
compiling dust.c
dust.c:2:20: error: malloc.h: No such file or directory
make: *** [dust.o ] Error 1
This is easy to get around - just remove the line:
#include <malloc.h>
from dust.c, as I think the malloc functions are provided from
stdlib.h on OSX.
And any other POSIX compliant OS:
http://www.opengroup.org/onlinepubs/009695399/functions/malloc.html>
The code is actually wrong to include <malloc.h> on Linux.
2. There was a problem with the -lexpat rule:
ccsr-2255b-g5 1004 % make all
compiling dust.c
compiling energy.c
compiling energy_data.c
compiling fasta.c
compiling lzw.c
compiling nucleotide.c
compiling util.c
compiling self.c
compiling SmithWaterman.c
compiling wublast.c
checking adt.a

checking util.a
ar rv ../util.a sht.o list.o Hashtable.o

a - sht.o

a - Hashtable.o
ranlib ../util.a
making g2c
compiling readWuBlast.c
making readwu
make: *** No rule to make target `-lexpat', needed by `libg2c.so'.
Stop.
The -lexpat rule is in the makefile at:
LIBG2C_OBJS = g2clib.o \
blast.o complementation.o complexity.o dust.o \
energy.o energy_data.o fasta.o lzw.o nucleotide.o
util.o \
self.o SmithWaterman.o wublast.o -lexpat \
${ADT_LIB} ${UTIL_LIB}
I'm presuming that it needs to link on the expat libraries for XML
parsing. I have expat 2.0 installed, with the following files on
my system:
/usr/local/lib/libexpat.a
/usr/local/include/expat.h
/usr/local/include/expat_external.h
To get around this, I simply copied libexpat.a to my working
directory.
Or you can specify it on the library include path with the option "-
L/usr/local/lib". There should be an LDFLAGS you can set for this,
and it's also probably a configure option.
3. -shared problem
ccsr-2255b-g5 1016 % cp /usr/local/lib/libexpat.a ./
ccsr-2255b-g5 1017 % make clean
.
.
.
ccsr-2255b-g5 1020 % make all
.
.
.
making g2c
compiling readWuBlast.c
making readwu
making libg2c.so
powerpc-apple-darwin8-gcc-4.0.1: unrecognized option '-shared'
/usr/bin/ld: Undefined symbols:
_main
collect2: ld returned 1 exit status
make: *** [libg2c.so] Error 1
Looking into Apple's docs, I found -dynamic is the replacement for
-shared on OSX (see http://developer.apple.com/technotes/tn2002/
tn2071.html#Section5), but still no success when I replace the
option:
making libg2c.so
/usr/bin/ld: Undefined symbols:
_main
collect2: ld returned 1 exit status
make: *** [libg2c.so] Error 1
If you could include the entire compilation line for one of the .o
files, that would be helpful.
A common cause of this is missing -fPIC or trying to use 'ld'
directly instead of using "g++" or "gcc" as the linker (whichever
is appropriate), but without the compilation line you are using,
there's no way to know what options you're adding that you
shouldn't, or are missing that you need to add.

I then tried -dynamiclib instead (I have no idea if I should do
this), which got me past the last error, but now this resulted in
a different error:
