Compiling liblscp for Mac OS X with XCode |
| 2 |
======================================== |
| 3 |
|
| 4 |
Requirements |
| 5 |
------------ |
| 6 |
|
| 7 |
The XCode project uses autotools build files. On Mac OS 10.4, you need |
| 8 |
to install pkg-config (available at http://pkgconfig.freedesktop.org/wiki/). |
| 9 |
|
| 10 |
If you are to build the CVS snapshot, then you need to do the following |
| 11 |
steps to make autotools work correctly: |
| 12 |
|
| 13 |
$ sudo ln -sf /usr/bin/glibtoolize /usr/local/bin/libtoolize |
| 14 |
$ sudo cat >/usr/local/bin/aclocal <<'EOF' |
| 15 |
#!/bin/sh |
| 16 |
/usr/bin/aclocal -I /usr/local/share/aclocal $@ |
| 17 |
EOF |
| 18 |
$ sudo chmod +x /usr/local/bin/aclocal |
| 19 |
|
| 20 |
Layout of the Directories |
| 21 |
------------------------- |
| 22 |
|
| 23 |
The XCode project for liblscp creates a temporary build directory as |
| 24 |
"$LIBGIG/../temp_build/$BUILD_STYLE" (where $LIBGIG is the libgig |
| 25 |
directory, and $BUILD_STYLE is the build style defined in the XCode |
| 26 |
project). In this directory, the following subdirectories are created |
| 27 |
and used: |
| 28 |
$BASE.build: |
| 29 |
Intermediate build directory. Symbolic links to the original |
| 30 |
source files are placed and "configure && make" is performed in |
| 31 |
this directory. ($BASE is the basename of the liblscp directory.) |
| 32 |
local: |
| 33 |
The product, liblscp.a, is "installed" in local/lib. |
| 34 |
Such a layout allows you to build binaries of different architectures |
| 35 |
(and build options) independently. On the other hand, you will need to |
| 36 |
link liblscp.a statically because you cannot expect other users to place |
| 37 |
liblscp.a at the same path. The XCode project takes care of this by |
| 38 |
giving "--disable-shared" to configure. |
| 39 |
|
| 40 |
Also note that this temporary directory is outside the liblscp directory |
| 41 |
and will be shared with the Xcode projects for other linuxsampler |
| 42 |
subproducts. So it is best to create a common directory for all |
| 43 |
linuxsampler subproducts and place the liblscp directory (and the |
| 44 |
directories of other linuxsampler subproducts) in it. |
| 45 |
|
| 46 |
Universal Binaries |
| 47 |
------------------ |
| 48 |
|
| 49 |
You can create the Universal Binaries by selecting "Deployment_UB" build |
| 50 |
style and build. The binaries for i386 and ppc architectures are built |
| 51 |
separately and then automatically combined. The products are found in |
| 52 |
$LIBLSCP/../temp_build/Deployment_UB/local/{bin,lib}. |
| 53 |
|
| 54 |
You can also create the binaries for i386 and ppc architectures |
| 55 |
separately by selecting "Deployment_i386" and "Deployment_ppc" built |
| 56 |
styles respectively. This may be more convenient when you make your |
| 57 |
binary exclusively for your own use. |
| 58 |
|
| 59 |
Note that the current XCode project does _not_ take care of liblscp.la |
| 60 |
and pkgconfig/lscp.pc when creating the Universal Binary. |
| 61 |
|
| 62 |
Additional Information |
| 63 |
---------------------- |
| 64 |
|
| 65 |
The XCode project just invokes autoconf_builder.sh after |
| 66 |
setting relevant environmental variables. If you are interested |
| 67 |
(or feel suspicious), please examine autoconf_builder.sh. |
