## Quick Start
|
||||
|
||||
For compilation of the C library run `make`.
|
||||
For compilation of the C library run `make`. You can also install the library and header file with `make install` (by default into `/usr/local/lib` and `/usr/local/bin`), but this can be changed by `make prefix=/some/dir`).
|
||||
|
||||
### Compiling on HP-UX
|
||||
Have HP aCC, GNU Make, and either GNU coreutils (`install`) or GNU libtool
|
||||
installed.
|
||||
|
||||
```
|
||||
$ gmake CC=/opt/aCC/bin/aCC CFLAGS="" PICFLAG='+z' C99FLAG=-Ae INSTALL=.. \
|
||||
WCFLAGS='+w' LDFLAG_SHARED=-b SOFLAG="-Wl,+h" \
|
||||
prefix=$PREFIX libdir=$PREFIX/lib/hpux32 install
|
||||
Alternatively, you can compile with `cmake`, e.g. by
|
||||
```sh
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ..
|
||||
make
|
||||
```
|
||||
|
||||
where `INSTALL` points either to `install` or `install-sh`, `PREFIX` points to
|
||||
your preferred target, e.g., `/opt` in System V Unix.
|
||||
### Using other compilers
|
||||
The included `Makefile` supports GNU/Linux flavors and MacOS with `gcc`-like compilers; Windows users will typically use `cmake`.
|
||||
|
||||
For other Unix-like systems and other compilers, you may need to pass modified settings to `make` in order to use the correct compilation flags for building shared libraries on your system.
|
||||
|
||||
For HP-UX with HP's `aCC` compiler and GNU Make (installed as `gmake`), you can compile with
|
||||
```
|
||||
gmake CC=/opt/aCC/bin/aCC CFLAGS="+O2" PICFLAG="+z" C99FLAG="-Ae" WCFLAGS="+w" LDFLAG_SHARED="-b" SOFLAG="-Wl,+h"
|
||||
```
|
||||
To run `gmake install` you will need GNU coreutils for the `install` command, and you may want to pass `prefix=/opt libdir=/opt/lib/hpux32` or similar to change the installation location.
