PKG_CHECK_MODULES considered harmful?

由 こ雲淡風輕ζ 提交于 2019-11-27 01:43:32
Various developers discourage the usage of the PKG_CHECK_MODULES (for example, in this answer ) but there is no clear, comprehensive explanation of their reasons as far as I've looked for. So, I ask: Why would PKG_CHECK_MODULES be harmful? What are the alternatives? I, for one, used it for the first time today. I found it invaluably useful, specially for dealing with pretty intricate library sets, such as GTK+, where I have all these dependencies: -I/usr/lib/i386-linux-gnu/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/pango-1.0 -I/usr

Autotools build fails due to subdir-objects option in AM_INIT_AUTOMAKE

由 谁说胖子不能爱 提交于 2019-11-26 21:53:33
问题 I'm currently working on a C++ project which relies on recursive automake for building. I want to build a shared library and the Makefile.am in the src directory of the library looks like # ... # Library name lib_LTLIBRARIES = libadapter-@MY_API_VERSION@.la # Sources libadapter_@MY_API_VERSION@_la_SOURCES = \ $(top_builddir)/src/sourceA.cpp \ $(top_builddir)/src/sourceB.cpp # ... Since version 1.14, automake issues a warning when the subdir-objects option is not specified in AM_INIT_AUTOMAKE

What's the difference of “./configure” option “--build”, “--host” and “--target”?

由 大城市里の小女人 提交于 2019-11-26 17:01:49
The script ./configure accepts 3 options --build , --host and --target . I'm confusing their roles. What's the difference and semantics of them? user124850 As noted in this blog post and alluded to in the GCC Configure Terms , --target only applies when you are compiling toolchains. When you are doing normal cross-compilation of a library or binary you use --build=the architecture of the build machine --host=the architecture that you want the file to run on However, when you are building toolchains, things can get more complicated. I think that the following is correct (though I can't say I've

How to determine host value for configure when using cross compiler

由 自古美人都是妖i 提交于 2019-11-26 14:08:41
问题 General question: If I use a cross compiler, how can I tell the value of the "--host" option I should give when I run configure? Specific: I'm using cross compiler for arm64 arch. What is the correct "--host" value to use? 回答1: If I use a cross compiler, how can I tell the value of the --host option I should give when I run ./configure ?
