Why does clang -dumpversion report 4.2.1

由 时光怂恿深爱的人放手 提交于 2019-12-08 15:40:27
问题 I was trying to use -dumpversion to determine if the compiler is usable. My project compiles with clang and newer gccs, but not with the old gcc 4.2.1. So why does clang pretend to be an old gcc? Extra questions, is it possible to change this value at runtime? Or does anyone have a nice autoconf macro to determine the compiler version with both clang and gcc? 回答1: Clang was originally written to be compatible with gcc 4.2.1. There has been some discussion about updating that number earlier

问题 My project requires dependency of libxml2 am using autotools to check the dependencies & install the same. I declare the dependency of using the following macro in configure.ac echo -n "checking if libxml2 is present... " PKG_CHECK_MODULES([LIBXML2], [libxml-2.0 >= 2.6.19], [echo "yes (features requiring libxml2 enabled)" AC_DEFINE(HAVE_LIB_XML, 1, [define if libxml2 is present])], [echo "no"] ) The macro works as desired in GNU/Linux . But somehow it fails in Solaris with the following error

问题 I'm using Autotools to compile Matlab modules. Originally, we used Libtool to accomplish, but it really does a terrible job dealing with Microsoft's compilers. As such, we are removing Libtool for Windows builds.

Automake Combine two static libraries into one

由 妖精的绣舞 提交于 2019-12-07 21:09:48
问题 I am trying to include symbols from a pre-built static library into a static library that I am building. The static library that I am building is then used inside of an executable. The problem I am having is that I am getting undefined symbols in my static library from the other static library. Which means the symbols I need from the pre-built static library are not being included in my static library. What is the correct approach with auto tools to do this? I know I need to un-archive the

Is there any documentation for building OS X frameworks using autotools?

由 老子叫甜甜 提交于 2019-12-07 13:29:04
问题 I have a cross-platform shared library, and I am using GNU autotools for the build system. I would like to be able to package the library as a framework on OS X. Is it possible to do this with autotools + additional scripting e.g. bash? Is there any good documentation for doing this, or does anyone know an example of a project that does this, which I could copy? 回答1: A framework is a glorified directory that includes a metadata file (Info.plist) and one or more libraries. I’m not sure if

“Help” string variable substitution for “configure --help”

问题 I have a string that I want to use multiple times for the output of configure --help . So I try doing something like this in configure.ac : AC_ARG_ENABLE([foobar], AS_HELP_STRING([--enable-foobar], [$foobar_help_str])) But no expansion or substitution is done, so the output is just $foobar_help_str . 回答1: Define the string as an M4 macro: m4_define([FOOBAR_HELP_STR], [Turn on the foobar features]) AC_ARG_ENABLE([foobar], [AS_HELP_STRING([--enable-foobar], FOOBAR_HELP_STR)]) 回答2: FYI, if you
