setprojectgrp.cpp
Eric J. Korpela authored
- Added checks for net/*.h, arpa/*.h, netinet/*.h and code to figure out
which of those files to include
- Modified MAC address check to work on some non-Linux unixes.
(mac_address.cpp)
- Added suggested change to "already attached to project" checking.
(ProjectInfoPage.cpp)
- changed includes of standard c header files to their c++ equivalents
(i.e. replaced <stdio.h> with <cstdio>) for namespace protection.
- replaced "using namespace std;" with more explicit "using std::function" in
several files.
- Fixed bug in checking whether the os is OS/2 and added conditional OS_OS2
to the build environment. (boinc_platform.m4,configure.ac)
- Changed build environment to not use -nostandardlibs unless we are using
G++ and static linkage is specified. (configure.ac)
- Added makefiles and package building files for solaris CSW package manager.
- Fixed bug with attempting to find login name using logname. (configure.ac)
- Added ifdef HAVE_* protection around some include files commonly found in
sys.
- Added support for unified binary for x86_64/i686-pc-solaris.
(cs_platforms.cpp)
- generate_host_cpid() now uses MAC address on non-linux unix.
(hostinfo_network.cpp)
- Macro BOINC_SET_COMPILE_FLAGS now doesn't check gcc only flags on non-gcc
compilers. (boinc_set_compile_flags.m4)
- Library compiles no longer depend upon the library extension or require
the library to be prefixed with lib.
- More fixes for fcgi builds.
- Added declaration of "struct ether_addr" and ether_ntoa(). Have not yet
implemented ether_ntoa() for machines that don't have it, or where it is
buggy. (unix_util.h)
- Added FCGI::perror() which calls FCGI_perror(). (boinc_fcgi.{h,cpp})
- Fixed library Makefiles so that all required headers get installed.
