## Quick Start ## 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 Alternatively, you can compile with `cmake`, e.g. by
Have HP aCC, GNU Make, and either GNU coreutils (`install`) or GNU libtool ```sh
installed. mkdir build
cd build
``` cmake ..
$ gmake CC=/opt/aCC/bin/aCC CFLAGS="" PICFLAG='+z' C99FLAG=-Ae INSTALL=.. \ make
WCFLAGS='+w' LDFLAG_SHARED=-b SOFLAG="-Wl,+h" \
prefix=$PREFIX libdir=$PREFIX/lib/hpux32 install
``` ```
where `INSTALL` points either to `install` or `install-sh`, `PREFIX` points to ### Using other compilers
your preferred target, e.g., `/opt` in System V Unix. 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.
