Should a “configure” script be distributed if configure.ac is available?

由 蹲街弑〆低调 提交于 2019-12-30 18:46:12
问题 Currently, our installation instructions are: autoreconf -fi ./configure ... The autoreconf step generates the configure file from configure.ac and Makefile.in from Makefile.in . If one of the dependencies (say pkg-config ) is not installed, both configure and autoreconf fail although the latter prints a cryptic error message. When releasing source tarballs, should the configure script be supplied in the package or not? What other files need to be included if it has to be distributed? The

How do I modify the install name of a .dylib at build time

问题 I am building the google-gflags commandline flags library for C++ on Mac OS X (10.7.1). The build process is as such: $ ./configure --prefix=output $ make $ make install I'd like to change the install name of the generated shared library at build time and not use install_name_tool afterwards. By default, the install name of the generated shared library, libgflags.dylib , is the output path: $ otool -L ./output/libgflags.dylib $ ./output/libgflags.dylib: /tmp/gflags-1.5/output/lib/libgflags.0

GNU autotools: Debug/Release targets?

由 霸气de小男生 提交于 2019-12-29 02:21:47
问题 I've been looking for this for a while: I'm currently converting a medium-size program to autotools, coming from an Eclipse-based method (with makefiles) I'm always used to having a "debug" build, with all debug symbols and no optimizations, and a "release" build, without debug symbols and best optimizations. Now I'm trying to replicate this in some way with autotools, so I can (perhaps) do something like: ./configure make debug Which would have all debug symbols and no optimizations, and

Cross-compiling for ARM with Autoconf

由 早过忘川 提交于 2019-12-28 05:53:05
问题 I am having trouble cross-compiling a library for my arm board using autconf. I am using this line: ./configure --target=arm-linux --host=arm-linux --prefix=/bla/bla/bla/linux_arm_tool CFLAGS='-m32' make make install When I do file to check it I get: libjpeg.so.8.4.0: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, not stripped That doesn't seem right at all, but I tried using it anyway... and I get: /usr/lib/gcc/arm-linux-gnueabi/4.5.3/../../../../arm-linux

Autoconf triplet for Android x86_64?

由 大憨熊 提交于 2019-12-25 04:45:19
问题 I wanted to examine the issue from this question: Android NDK for x86_64 has no reference for bcopy and index. In the question, the poster asked about Android x86_64 and bcopy in relation to the Lame sound library. I set up my cross-compile environment, set the paths for tools and sysroot, and exported the usual suspects like CC , CXX CFLAGS , CXXFLAGS , etc. For example: $ echo $CC x86_64-linux-android-gcc $ which x86_64-linux-android-gcc /opt/android-ndk-r10d/toolchains/x86_64-4.9/prebuilt

configure.ac: Library and headers not usable and not present

由 你离开我真会死。 提交于 2019-12-25 02:23:26
问题 I have implemented a logging library in C (which I've named liblogger), and used Autotools to compile and install it. As far as I can see, the installation is correctly done, since the headers and the library itself (which I currently bundle into a static library) are installed into the appropriate directories (/usr/local/include/liblogger/ for the headers and /usr/local/lib for the .a). Now I am trying to link another tool with that library (compiled and built also using Autotools). To check

Find the GCC Version

由 孤街浪徒 提交于 2019-12-24 12:14:28
问题 Using autoconf/automake how does one find the GCC version on the system? To get the python version installed you'd use AM_PATH_PYTHON, and then the PYTHON_VERSION variable would be available. Is there something similar for the GCC version? (Also, is it possible to get the major, minor and patch level of gcc?) 回答1: A quick search reveals the ax_gcc_version macro which should give you the GCC_VERSION variable. Unfortunately, that macro depends on AX_GCC_OPTION which has recently been deprecated
