Before we add any targets to the configuration, it is often useful to first capture a record of what the traditional build does, and save the output of the configuration and the build step into a log file. For our Vim example, this can be done using the following:

$ ./configure --enable-gui=no

... lot of output ...

$ make > build.log

In our case (the complete content of build.log is not shown here), we are able to verify which sources are compiled and which compile flags are used (-I. -Iproto
-DHAVE_CONFIG_H -g -O2 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=1). From the log file, we can deduce the following:

• All objects are linked into a single binary
• No libraries are produced
• The executable target is linked against the following libraries: -lSM -lICE -lXpm -lXt -lX11 -lXdmcp -lSM -lICE -lm -ltinfo -lelf -lnsl -lacl -lattr -lgpm -ldl
