# The gamma launcher runs the JDK from $JAVA_HOME, overriding the JVM with a
|
|
|
56 |
# freshly built JVM at ./libjvm.{so|dylib}. This is accomplished by setting
|
|
|
57 |
# the library searchpath using ({DY}LD_LIBRARY_PATH) to find the local JVM
|
|
|
58 |
# first. Gamma dlopen()s libjava from $JAVA_HOME/jre/lib{/$arch}, which is
|
|
|
59 |
# statically linked with CoreFoundation framework libs. Unfortunately, gamma's
|
|
|
60 |
# unique searchpath results in some unresolved symbols in the framework
|
|
|
61 |
# libraries, because JDK libraries are inadvertently discovered first on the
|
|
|
62 |
# searchpath, e.g. libjpeg. On Mac OS X, filenames are case *insensitive*.
|
|
|
63 |
# So, the actual filename collision is libjpeg.dylib and libJPEG.dylib.
|
|
|
64 |
# To resolve this, gamma needs to also statically link with the CoreFoundation
|

|
65 |
# framework libraries.
