EPICSSNS-CSS-3.2.6-LINUX 32位版本 EPICS Control System Studio (CS

This plugin provides EPICS ChannelAccess libraries, initializing their settings from Eclipse preferences. For GUI Applications, consider adding org.csstudio.platform.libs.epics.ui. * JCA .. is the basic Java Channel Access API, including an implementation that uses the original EPICS libraries via JNI. Binaries for JCA are in OS-specific fragments org.csstudio.platform.libs.epics.macosx, org.csstudio.platform.libs.epics.linux, .. * CAJ .. is a pure Java implementation of the JCA API. Examples for building JCA JNI Binaries -------------------------------------- Get sources for JCA from http://epics-jca.sourceforge.net/jca: > hg clone http://epics-jca.hg.sourceforge.net:8000/hgroot/epics-jca/epics-jca > cd epics-jca > hg update JCA_20120614_2_3_6 Set EPICS_BASE_RELEASE, HOST_ARCH, EPICS_HOST_ARCH as required to build EPICS base. > ant This creates two items of interest: 1) Java library O.core/jca.jar, like the one in this plugin's lib subdir 2) OS-specific JNI lib like O.darwin-x86/libjca.jnilib, which typically should be re-linked as described below and then placed into the corresponding lib/<OS>/<CPU> subdir of the fragment for that OS. - Mac OS X Created on Intel OS X 10.6.8 with EPICS base R3.14.12.2 java 1.6.0_31. The 'ant' build ends like this: g++ -L/Kram/epics/R3.14.12.2/base/lib/darwin-x86 -lca -lCom -framework JavaVM \ -arch i386 -dynamiclib -Wl,-single_module \ -o /Kram/MerurialRepos/jca/O.darwin-x86/libjca.jnilib \ /Kram/MerurialRepos/jca/O.darwin-x86/JNI.o ... which resulted in a shared library with further shared lib dependencies: otool -L O.darwin-x86/libjca.jnilib O.darwin-x86/libjca.jnilib: ... /Kram/epics/R3.14.12.2/base/lib/darwin-x86/libca.3.14.12.dylib (compatibility version 3.14.0, current version 3.14.12) /Kram/epics/R3.14.12.2/base/lib/darwin-x86/libCom.3.14.12.dylib (compatibility version 3.14.0, current version 3.14.12) ... Manually issuing the following command creates a JCA JNI lib with only "system" dependencies, no remaining EPICS shared lib dependecies: LIB=$EPICS_BASE_RELEASE/lib/$EPICS_HOST_ARCH g++ -framework JavaVM -arch i386 -dynamiclib -Wl,-single_module -o O.darwin-x86/libjca.jnilib \ O.darwin-x86/JNI.o $LIB/libCom.a $LIB/libca.a cp O.darwin-x86/libjca.jnilib ....../org.csstudio.platform.libs.epics.macosx/lib/macosx/x86/libjca.jnilib - Linux X86 Created on Red Hat Enterprise Linux AS release 4 (Nahant Update 8) with EPICS base R3.14.11, JDK 1.6.0_21 Similar to the OS X binary, the JNI lib was linked without further dependencies on shared EPICS base libraries: cd O.linux-x86 LIB=$EPICS_BASE_RELEASE/lib/$EPICS_HOST_ARCH g++ -shared -lpthread -lreadline -lncurses -lm -lrt -Wl,-rpath,. -o libjca.so JNI.o $LIB/libca.a $LIB/libCom.a # Check: ldd -d libjca.so cp libjca.so ....../org.csstudio.platform.libs.epics.linux/lib/linux/x86/libjca.so - Linux X86_64 Red Hat Enterprise Linux Workstation release 6.2 (Santiago) with EPICS base R3.14.12.2, JDK 1.6.0_31 cd O.linux-x86_64 ldd libjca.so # Showed dependencies on libca.so, ...

Created on Intel OS X 10.5.8, java 1.5.0_24 by running ant cp target/caj.jar ....../org.csstudio.platform.libs.epics/lib/caj-1.1.7.jar jca-2.3.2.jar was built from jca-2.3.2 sources with the following changes: src/core/gov/aps/jca/jni/JNI.cpp, line 1112 // KUK, Mar 31 2009: Leaked memory from ....addMonitor() delete ((MonitorID*)monitorID); jca-2.3.1.jar was built from the jca-2.3.1 sources with the following changes: - Updated ThreadSafeContext.java. Based on findings by Tom Pelaia and Kay Kasemir, the pause() call in the run() loop was replaced by a blocking queue. The original implementation would be quite slow on fast CPUs(!) because the code would sit in pause() instead of handling requests. Now it wakes immediately when new requests arrive. - JNITargetArch.java checks for Mac OS X handled osarch="ppc" and "x86", but latest Intel Macs seem to report "i386", which is now handled as well.
