GNU Compiler for C

===================================

gcc -O2 -Wall -pedantic program.c

gcc -M -H -O3 -E program.c

gcc -O0 -Wall -ansi program.c

gcc -Wall -I /tmp/include -L /tmp/lib program.c

This is a standard bit of advice

===================================

The static program will use less memory

The static program will not use new versions of shared libraries as they become available, and thus may avoid breakage and bugs

The static program will load and execute more quickly

The static program need not have an open source license, while the shared library version cannot be closed source

Yes, some bugs can be avoided

===================================

gcc -ldd /usr/bin/cp

ldd $(which cp)

You can run ldd indirectly on the executable using which

ldd /usr/bin/cp

You can run ldd directly on the executable

find -libso /usr/bin/cp

===================================

Use of shared libraries can cause bugs because the application may conflict with the new library version

Unfortunately, there may be unforeseen problems and inadequate testing

Applications can load faster when using shared libraries

If the relevant data is already in memory it need not be loaded again

Use of shared libraries saves memory

Only one copy of the library needs to be kept in memory if more than one application is using its contents

Use of shared libraries enables applications to stay up to date with new library features without being recompiled

The application will automatically use the new features
