Subject: Changed FMIL core and fragments logic to properly find files
X-Git-Url: https://gerrit.simantics.org/r/gitweb?a=commitdiff_plain;h=refs%2Fchanges%2F64%2F1664%2F5;p=simantics%2Ffmil.git

Changed FMIL core and fragments logic to properly find files

Required .dll and .so files on window and linux are found in fragments
.win32, .win64 and .linux64. Added a "Requires-Capability" and
"Provides-Capability" tag to the project's MANIFEST.MF files, which now
correctly resolves the fragments on Linux and Windows.

Also added first build of linux FMI shared object files (still missing
FMUSimulator.so!)

Amend 1: Updated to tycho 1.1.0 build

Amend 2: Added README.md to linux64 FMI Library with build from source
instructions

+Build FMI Library for Linux:
+Download 2.0.3-src.zip from here http://www.jmodelica.org/FMILibrary
+Derived guide: http://www.jmodelica.org/page/27916
+
+1) Download cmake (apt-get install -y cmake)
+2) Unzip the source file to a source directory (/path/to/source)
+3) Make an empty build directory (mkdir /path/to/build)
+4) Change directory to the build directory
+5) cmake /path/to/source
+6) make
+7) make install test
+	7.1) If tests fail, look at the error and fix it
+	7.2) Otherwise move on to step 8.
+8) Under your build directory should be five files:
+	- libfmu1_dll_me.so
+	- libfmu2_dll_me.so
+	- libfmu1_dll_cs.so
+	- libfmu2_dll_cs.so
+	- libfmilib_shared.so
+9) Copy the above files to where you want them (i.e. under org.simantics.fmil.linux64 libraries directory)
+10) Repeat steps 3 to 9 for "debug" shared objects, but replace the following steps:
+	"5") cmake -DFMILIB_ENABLE_LOG_LEVEL_DEBUG=ON /path/to/source (note the added param)
+	"9") Copy the files to libraries/debug directory (instead of libraries)
