#+TITLE: runcap
* Overview
The function *runcap* runs an external command, and waits for its
termination, optionally capturing its standard output and standard
error streams, and piping data to its standard input.
* Building as a standalone library
The following steps will build the project as a standalone installable
library:
1. Configure the package
#+BEGIN_SRC shell-script
./configure
#+END_SRC
2. Build the project.
#+BEGIN_SRC shell-script
make
#+END_SRC
3. Install the files (normally run as root).
#+BEGIN_SRC shell-script
make install
#+END_SRC
This will install the files *libruncap.so* and *libruncap.a* to the
system library directory, and the header file *runcap.h* to the
system include directory.
* Incorporating as a submodule
To incorporate *runcap* as a submodule to your project, follow these
steps:
1. Change to your project's toplevel directory.
2. Clone the project.
#+BEGIN_SRC shell-script
git submodule add git://git.gnu.org.ua/runcap.git
git submodule init
#+END_SRC
3. Add it to *git* index:
#+BEGIN_SRC shell-script
git add runcap
#+END_SRC
4. Add it to your toplevel *Makefile.am*.
#+BEGIN_SRC make
ACLOCAL_AMFLAGS = -I grecs/am
SUBDIRS = runcap
#+END_SRC
5. Edit your *configure.ac*
#+BEGIN_SRC automake
RUNCAP_SETUP
#+END_SRC
6.
#+BEGIN_SRC make
AM_CPPFLAGS = @RUNCAP_INC@
AM_LDADD = @RUNCAP_LDADD@
#+END_SRC
# Local Variables:
# mode: org
# paragraph-separate: "[ ^L]*$"
