can not autoconf for cgminer (missing AC_CHECK_FUNCS)

Question

I try to build cgminer for server from the source-code

since it make by autoconfig and automake, I use autoscan try to scan it. but the problem is: missing AC_CHECK_FUNCS and other missing, what the source file or library I missed?

may command in shell is:

Answer 1

You're not missing anything. autoscan is not something you should be running unless you are the package maintainer, and it is overly verbose about checking for functions. These warnings are simply telling you that the configure script will not be checking for the named functions, headers, or variable types but a cursory scan of the list does not give rise to any real concerns. The maintainers have constructed a configure.ac that appears to assume the user is using a relatively modern system and a C compiler that recognizes the restrict keyword. Personally, if I were maintaining the package, I would add the checks for AC_C_RESTRICT and AC_C_INLINE and probably a few others, but as a user you can safely ignore these warnings. If you are just trying to build the package, don't run the autotool chain; just get a source package that has already built the necessary files and build it from that.

Answer 2

Autoscan is only when you're creating a new package from scratch. Use

./configure
make
sudo make install
