using homebrew apxs from homebrew apache httpd24 fails with libtool: compile: unable to infer tagged configuration
$ apxs -i -c -Wc,"-arch x86_64" -Wl,"-arch x86_64 " mod_uwsgi.c

libtool: compile: unable to infer tagged configuration
libtool: compile: specify a tag with `--tag'
apxs:Error: Command failed with rc=65536
.
What environment must I export to have libtool not complain about tag?
after digging through the source I found that if LTFLAGS is set to --tag=cc things work.
$ LTFLAGS=--tag=cc apxs -i -c mod_uwsgi.c

I get an error when compiling (configure) Apache httpd. Please tell me how to solve it.

The "configure" problem has probably been solved. (I stopped using github). However, an error occurs during make.

I want to compile my own Apache module when building my image, so i wrote the following Dockerfile.
FROM httpd:2.4.25
COPY conf/httpd.conf /usr/local/apache2/conf/httpd.conf
COPY modules/mod_example.c /usr/local/apache2/modules/mod_example.c
RUN apxs -i -a -c modules/mod_example.c
EXPOSE 80
But i get an error :
/usr/share/apr-1.0/build/libtool --silent --mode=compile x86_64-linux-gnu-gcc -std=gnu99 -prefer-pic -DLINUX -D_REENTRANT -D_GNU_SOURCE -pthread -I/usr/local/apache2/include -I/usr/include/apr-1.0 -I/usr/include/apr-1.0 -I/usr/include -c -o mod_example.lo mod_example.c && touch mod_example.slo

I tried apt-get install gcc or libtool it say it's unable to locate the package.
My goal is to compile the ".c" file in a ".so" file.
Installing gcc, or the build-deps of say libapr1, is all that's needed. You probably just have a problem with your unspecified attempt at adding the compiler from your dockerfile.
For referene, here's how the httpd layer adds the compiler:
https://github.com/docker-library/httpd/blob/master/2.4/Dockerfile
I needed to do an apt-get update then :
apt-get install build-essential libtool
Since the docker image is a prod image, it doesn't contain dev tools.
I want to setup the ct-ng for my gui application and now I want to use wxwidgets.
For setting up the crosstool, I have used:
# Install prerequisites:
apt-get -y install gcc gperf bison flex gawk libtool automake libncurses5-dev texinfo
# Setup toolchain
# instructions from https://github.com/crosstool-ng/crosstool-ng
cd toolchain/crosstool-ng
./bootstrap
./configure --prefix=$HOME/.local
make && make install
echo -ne "\n\nif [ -d \"$HOME/.local/bin\" ]; then\n PATH=\"$HOME/.local/bin:$PATH\"\nfi" >> ~/.profile
source ~/.profile
mkdir ../tc/
cd ../tc/
ct-ng list-samples

make
The only way I have found is to clone wxwidgets from github and compile it as above in the script. Then, I included as path -I
WXWIDGET=../toolchain/wxWidgets/include/
$(CXX) -I$(FLEX) -I$(WXWIDGET) $(WXWIDGETSFLAGS) $(CPPFLAGS) $(header) $(src) $(obj3) -o $(OUTPUT)/$(bin)
Hundreds of errors appearing while compiling:

What should I do?
You need to try "--host" and "--target" configure options.
Just try "../configure --host=x86_64-w64-mingw32 --target=x86_64-w64-mingw32 --disable-shared --enable-unicode".
BTW, "--enable-unicode" should be turned on by default. So you can drop it.
Also, if you software required C++11, you should compile the library as:
CXXFLAGS="-std=c++11" ../configure --host=x86_64-w64-mingw32 --target=x86_64-w64-mingw32 --disable-shared --enable-unicode
I am so frustrated installing reverse-proxy-related modules to Apache2 HTTP server on a CentOS 5 box. Since it's an old version of Apache2 server, I had to compile the modules from source using Apache tool 'apxs'. I got no warnings or errors installing the module by 'apxs' but got runtime error when trying to restart the Apache server.
Starting httpd: httpd: Syntax error on line 206 of /etc/httpd/conf/httpd.conf: Cannot load /usr/lib64/httpd/modules/mod_xml2enc.so into server: /usr/lib64/httpd/modules/mod_xml2enc.so: undefined symbol: xmlDetectCharEncoding
[FAILED]
The following are more details.
OS: CentOS 5.11; Linux 2.6.18-400.1.1.el5 #1 SMP Thu Dec 18 00:59:53 EST 2014 x86_64 x86_64 x86_64 GNU/Linux
Apache: version 2.2.3
For historical reason, I cannot upgrade either of them to newer version to fix the issue.
The OS was originally lack of libxml2, which I installed by yum successfully with no issue. I downloaded the source files of mod_proxy_html including 1) mod_xml2enc.c, 2) mod_proxy_html.h and 3) mod_proxy_html.c
I used the following commands to at first install mod_xml2enc and then mod_proxy_html.
apxs -i -a -c -I /usr/include/libxml2/ mod_xml2enc.c
apxs -i -a -c -I /usr/include/libxml2/ -I ./ mod_proxy_html.c
Both seemed OK and showed some output like the following:

Libraries have been installed in:
/usr/lib64/httpd/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

chmod 755 /usr/lib64/httpd/modules/mod_xml2enc.so
[activating module `xml2enc' in /etc/httpd/conf/httpd.conf]
However, when I tried to restart the server, the error message I put at the top was raised.
I've tried many ways to fix this issue, however, nothing worked. Maybe it's worth noting that I took the exact steps installing the same modules on a CentOS 5.11 32bit machine and got no problem at all. The only difference between these two machines is just one is 32-bit and the other is 64-bit.
Hope someone would know how to fix this issue.
Thanks a lot in advance.
I found the solution to this issue on my own. It is a stupid one. I forgot to load the libxml2 to the Apache server. After I added LoadFile /usr/lib64/libxml2.so, the error was gone.

While using GCC, it compiles fine, but clang does not.
On a fresh install of Ubuntu 12.10 I installed the following packages:
$ sudo apt-get install build-essential
$ sudo apt-get install clang
$ sudo apt-get install gnustep
$ sudo apt-get install gnustep-make
$ sudo apt-get install gnustep-devel
$ sudo ln -s /usr/lib/gcc/i686-linux-gnu/4.7/include/objc /usr/local/include/objc
(the final symlink is required to properly locate the objc.h header)
Then I compiled the test.m file as follows:
$ clang -o test test.m -I `gnustep-config --variable=GNUSTEP_SYSTEM_HEADERS` \
-L `gnustep-config --variable=GNUSTEP_SYSTEM_LIBRARIES` \
-lgnustep-base -fconstant-string-class=NSConstantString \
