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-8.3 platform.

Installation of NSPR

Install NSPR by running the following commands:

cd nspr                                                     &&
sed -ri 's#^(RELEASE_BINS =).*#\1#' 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) &&

This package does not come with a test suite.

Now, as the root user:

make install

Command Explanations

sed -ri 's#^(RELEASE_BINS =).*#\1#' 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.
