NSPR-4.35

Introduction to NSPR

Netscape Portable Runtime (NSPR) provides a platform-neutral API for system level and libc like functions.

This package is known to build and work properly using an LFS 12.0 platform.

Package Information

Installation of NSPR

Install NSPR by running the following commands: 

cd nspr                                                     &&
sed -ri '/^RELEASE/s/^/#/' pr/src/misc/Makefile.in &&
sed -i 's#$(LIBRARY) ##'   config/rules.mk         &&

./configure --prefix=/usr \
            --with-mozilla \
            --with-pthreads \
            $([ $(uname -m) = x86_64 ] && echo --enable-64bit) &&
make

The test suite is designed for testing changes to nss or nspr and is not particularly useful for checking a released version (e.g. it needs to be run on a non-optimized build with both nss and nspr directories existing alongside each other). For further details, see the Editor Notes for nss at https://wiki.linuxfromscratch.org/blfs/wiki/nss

Now, as the root user: 

make install

Command Explanations

sed -ri '/^RELEASE/s/^/#/' pr/src/misc/Makefile.in: This sed disables installing two unneeded scripts.

sed -i 's#$(LIBRARY) ##' config/rules.mk: This sed disables installing the static libraries.

--with-mozilla: This parameter adds Mozilla support to the libraries (required if you want to build any other Mozilla products and link them to these libraries).

--with-pthreads: This parameter forces use of the system pthread library.

$([ $(uname -m) = x86_64 ] && echo --enable-64bit): The --enable-64bit parameter is required on an x86_64 system to prevent configure failing with a claim that this is a system without pthread support. The [ $(uname -m) = x86_64 ] test ensures it has no effect on a 32 bit system.

Short Descriptions

nspr-config

provides compiler and linker options to other packages that use NSPR

libnspr4.so

contains functions that provide platform independence for non-GUI operating system facilities such as threads, thread synchronization, normal file and network I/O, interval timing and calendar time, basic memory management and shared library linking

libplc4.so

contains functions that implement many of the features offered by libnspr4

libplds4.so

contains functions that provide data structures
