+ o LyX can be compiled on Tru64 Unix with either GNU's gcc or the default
+ Compaq cxx compiler.
+
+ There are no Alpha-specific problems with gcc.
+
+ The following notes all refer to compilation with the Compaq cxx compiler.
+
+ LyX cannot be compiled on Tru64 Unix 4.0d or 4.0e with the default cxx
+ compiler. You should upgrade to at least cxx V6.2, to be found at
+ ftp::/ftp.compaq.com/pub/products/C-CXX/tru64/cxx/CXX622V40.tar. Users
+ running Tru64 Unix 4.0f and greater should have no real problems compiling
+ LyX.
+
+ cxx V6.2 will compile LyX out of the box.
+ cxx V6.3-020 is also known to work, although there is a bug in
+ /usr/include/cxx/deque that will break compilation in FormPreferences.C.
+ Compaq are investigating, but a patch that works /now/ is:

+ At the time of writing, cxx V6.5-026 is the latest cxx compiler. It is
+ /not/ recommended. Not only do the bugs in the system header files still
+ exist, but the compiler itself appears to be both buggy and extremely
+ bloated (trebles the size of the stripped LyX binary).
+
+ In order to compile LyX with the cxx compiler, you should run configure
+ with the following flags:
+ CXX='cxx -std strict_ansi'
+ CXXFLAGS='-nopure_cname -nocleanup -ptr /tmp/lyx_cxx_repository -O2'
+ CC='cc -std1'
+ The -nopure_cname flag is needed for compilers V6.3 and above because
+ LyX makes use of functions like popen, pclose that are defined in the
+ c version of <stdio.h> but are not formally part of any c/c++ standard.
+ They are not, therefore, included in the <cstdio> header file.
