I try to install eigen3.3.7 with cmake on ubuntu 16 but cmake fails.
I follow the INSTALL file hints :
1) I extract the tar archive
2) Make a "build" dir named buildDir
3) Go to build dir : cd buildDir
4) Start cmake : cmake ../Eigen
Then the cmake process ends up with the error :
CMake Error at CMakeLists.txt:1 (include):
include could not find load file:
RegexUtils
CMake Error at CMakeLists.txt:2 (test_escape_string_as_regex):
Unknown CMake command "test_escape_string_as_regex".
May I ask you some hints please ?
Regards
Sylvain
I followed the advices of chtz, but it still fails, see below the console output :

Thanks for helping.
This sequence of commands seems to work properly after downloading (in my case the currently latest version eigen-3.3.7):
bunzip2 eigen-3.3.7.tar.bz2
tar -xvf eigen-3.3.7.tar
cd eigen-3.3.7/
mkdir build
cd build
cmake ../.
sudo make install

I tried:
cd ~
git clone git://github.com/stephane/libmodbus
cd libmodbus
./autogen.sh
./configure --enable-static
make
sudo make install
sudo cp ./src/.libs/libmodbus.a /usr/local/lib/
to download, compile and install the libmodbus library. Now I have a libmodbus.a file in /usr/local/lib/.
Now I want to install mbrtu:
cd ~
git clone https://github.com/gitaeuber/mbrtu
cd mbrtu
make
sudo make install
Strangely, after make I get the error:
In file included from mbrtu.c:22:
mbrtu.h:25:12: fatal error: modbus.h: No such file or directory
25 | #include <modbus.h>
| ^~~~~~~~~~
compilation terminated.
make: *** [Makefile:9: mbrtu] Error 1
I tried adding the library path /usr/local/lib/ to $LD_LIBRARY_PATH, but that did not help at all.
Can someone explain me how I can compile and install the libmodbus library correctly?
It is not a library that is not found by the linker but an include file which is not found by the compiler. Look at the make file install to see how include files are searched. It is likely a variable INC or INCLUDE.
I'm trying to build libwebsockets library using minGW by following the steps available at https://github.com/warmcat/libwebsockets/blob/master/READMEs/README.build.md
under the section
#section cmwmgw Building on Windows (MinGW)
I'm doing
cmake -G "MSYS Makefiles" -DCMAKE_INSTALL_PREFIX=C:\Users\pro12\Desktop\lib\libwebsockets
the directory "C:\Users\pro12\Desktop\lib\libwebsockets" contains the source files for the libwebsockets library and I'm runnning this command from
C:\Users\pro12\Desktop\libwebsockets\build
but it giving me error
CMake Error: The source directory "C:/Users/pro12/Desktop/libwebsockets/build" does not appear to contain CMakeLists.txt.
Can anyone tell what i'm doing wrong here? Thanks
Since you are building it in C:\Users\pro12\Desktop\libwebsockets\build, but your source code is in C:\Users\pro12\Desktop\libwebsockets, obviously cmake could not find the CMakeLists.txt, try
cmake -G "MSYS Makefiles"
-DCMAKE_INSTALL_PREFIX=C:\Users\pro12\Desktop\lib\libwebsockets ..
Do not omit the .. two tailing dots: these indicate the parent directory!
Your libwebsockets "CMakeLists.txt" file is exist in
"C:/Users/pro12/Desktop/libwebsockets"
but your "cmake" CMD is running in
"C:/Users/pro12/Desktop/libwebsockets/build"
so , you should:
cmake .. -G "MSYS Makefiles"
-DCMAKE_INSTALL_PREFIX=C:\Users\pro12\Desktop\lib\libwebsockets
it can specify "CMakeList.txt" file's directory
I am working on a system on which I am a non-root user.
While trying to install gcc 5.1 in a custom directory as the present shared version of gcc isn't working for postgresql installation, I started out by
wget gcc 5.1.
After unzipping the folder, ran the commands below:
cd /seq/genome_portal/lib
mkdir bld
mkdir gcc
cd bld
/seq/genome_portal/lib/gcc-5.1/configure --prefix=/seq/genome_portal/lib/gcc
However config.log still shows this error:
/../../redhat_6_x86_64/pkgs/gcc_4.9.0/libexec/gcc/x86_64-redhat-linux/4.9.0/cc1: error while loading shared libraries: libmpfr.so.4: cannot open shared object file: No such file or directory
The prerequisites that come after
./contrib/download_prerequisites
are gmp,mpfr and mpc. I started with gmp and ended up in the same error as above. I somehow need to tell these programs that I do not want to use the existing gcc.
But I get the same error as mentioned before. Any advice as to how I can proceed to install it?
Building a compiler is much more complicated that building a straightforward utility; just running configure is not enough.
Primarily, you need to read the instructions; they are provided in the GCC source directory in the INSTALL subdirectory. They are in HTML so point your browser at it.
I know you didn't do this yet because the step on configuration makes very clear you should be using an out-of-source configuration; e.g., something like:
mkdir ../bld
cd ../bld
../gcc-5.1/configure ...
rather than running ./configure.
Regarding the missing dependencies, there's a "prerequisites" section in the docs. To get MPFR and other helpful things you can run:
cd gcc-5.1
./contrib/download_prerequisites
ETA: This should work:
rm -rf newgcc
mkdir newgcc
cd newgcc
tar xzf gcc-5.1.tar.gz
cd gcc-5.1
./contrib/download_prerequisites
mkdir ../bld
cd ../bld
../gcc-5.1/configure <configopts>
make -j8
make install
(or whatever -j you prefer).
I have a source code tree as follows
daily_build
->src_dir1
->src_dir2
..
We have been using cmake-gui to configure and generate for Visual Studio 8 2005.
However, on a separate machine, we are trying to automate the build process for nightly builds.
In order to this we are trying to run cmake from command line as follows
1) vcvars32.bat
2) svn co <url path> D:\daily_build
3) cd daily_build\build\gen\host
4) cmake -G"NMake Makefiles" D:\daily_build
However, CMake exits with error
CMake Error :CMake was unable to find a build program corresponding to "NMake Makefiles"......
However, in the very same prompt, I can run cl.exe and nmake.
Further, If I look in the CMakeFiles folder, there is no error.log. All I can see is CMakeOutput.txt and the ouput file shows that CMakeCCompilerId.exe and CMakeCXXCompilerId.exe were both generated successfully.
Does anyone have any ideas what am I doing wrong?
So I created ffmpeg configuration file that makes it pure C (platform independent, but only theoretically)
So my config is simple (0.6.1,0.6.3 tested):
./configure --disable-doc --disable-ffplay --disable-ffprobe --disable-ffserver --disable-avdevice --disable-avfilter --disable-pthreads --disable-everything --enable-muxer=flv --enable-encoder=flv --enable-encoder=h263 --disable-mmx --disable-shared --prefix=bin/ --disable-protocols --disable-network --disable-optimizations --disable-debug --disable-asm --disable-stripping
Compiling this on Linux will resolve in 4 libs with totall size of 1 mb.
But I need to compile ffmpeg with custom compiler (opensource gcc analog called Adobe Alchemy, lets us compile C/c++ into Flash)
It gives me errors on nearly each and every file during standart Make:
Array #ARGV missing the # in argument 1 of shift() at /home/rupert/Downloads/alchemy-ubuntu-v0.5a/achacks/gcc line 218.
cc1: error: unrecognized command line option "-Wtype-limits"
cc1: error: unrecognized command line option "-fno-signed-zeros"
So what shall I do - how to compile ffmpeg (at least smallest part of it) via alchemy?
Update
If we would fix that errors manually (2 in configure.mak and one in alchemy gcc) we would get a really messy and long output like:
> $ make -w install
make: Entering directory `/home/rupert/Downloads/ffmpeg-0.6.1'

FlasCC(Alchemy 2) does compile ffmpeg fine - for anyone who is trying, basically you need to download ffmpeg source. Go to ffmpeg directory, do
PATH=/cygdrive/c/PATH_TO_FLASCC/sdk/usr/bin:$PATH ./configure --prefix=/cygdrive/c/PATH_TO_FLASCC/sdk/usr
Now it's good if you run configure with some restrictions so it doesn't include every codec or filter there is(takes ages). Additional configure params from my use case:
--disable-ffserver --disable-everything --enable-filter=scale --enable-demuxer=flv --enable-muxer=ogg --enable-protocol=file --disable-network --disable-debug --disable-yasm --disable-asm --disable-stripping --enable-memalign-hack --disable-shared --enable-decoder=flashsv --enable-encoder=mpeg1video --enable-encoder=libtheora --enable-encoder=libvorbis --enable-libtheora --enable-libvorbis
Important is to --disable-everything and then enable only what you need.
Then run ./make and ./make install (with the PATH in front of those commands), it should produce and install ffmpeg libs.
When I built a test swf, all seemed to work. I've used their (modified) sample where they encode 25 dummy mpeg frames. I'm tracing the encoding progress at least and seeing the frames being encoded.
SWC is a problem though, if you would want to use that. I'm getting strange errors - first it couldn't find codec(got NULL when using the find codec function), when I specified it by name, it can't allocate codec context(also got NULL). Then I compiled it in pure Flex and it got over this one, but couldn't open the codec (basically all of those are av_ something library functions). I really don't understand why SWC doesn't work with these as with emit-swf all works perfectly fine.
Maybe someone could enlighten on the SWC / SWF differences.
There was some discussion about this on the Adobe Forums here. It seems rather involved, though some folks seem to have made some progress.
Try it with the new flash c compiler Adobe Flash cc. I hope it may help you to compile ffmpeg in flash.
