User Notes:

Installation of libgcrypt

Install libgcrypt by running the following commands:

./configure --prefix=/usr &&

Only info documentation is shipped in the package tarball. If you wish to build alternate formats of the documentation, (you must have texlive-20140525 installed to build the PDF and PostScript documentation), then issue the following commands:

make -j1 -C doc pdf ps html &&
makeinfo --html --no-split -o doc/gcrypt_nochunks.html doc/gcrypt.texi &&
makeinfo --plaintext       -o doc/gcrypt.txt           doc/gcrypt.texi

To test the results, issue: make check.

Now, as the root user:

make install &&
install -v -dm755   /usr/share/doc/libgcrypt-1.6.2 &&
install -v -m644    README doc/{README.apichanges,fips*,libgcrypt*} \

If you built the additional documentation, install it by issuing the following commands as the root user:

install -v -dm755   /usr/share/doc/libgcrypt-1.6.2/html &&
install -v -m644 doc/gcrypt.html/* \
                    /usr/share/doc/libgcrypt-1.6.2/html &&
install -v -m644 doc/gcrypt_nochunks.html \
                    /usr/share/doc/libgcrypt-1.6.2 &&
install -v -m644 doc/gcrypt.{pdf,ps,dvi,txt,texi} \
