| Hi!
| 
| I tried to build Ovtave 2.1.50 on a HP GS1280 running Tru64 V5.1B, with the 
| Compaq C++ Compiler V 6.5.  I configured with 
| 
| CC=cc
| MAKE=gmake
| CXX=cxx
| F77=f77
| CFLAGS=-ieee -O3 -arch ev7 -tune ev7
| CXXFLAGS=-ieee -O3 -arch ev7 -tune ev7
| 
| ./configure CPPFLAGS=-I/opt/nlh/include LDFLAGS=-L/opt/nlh/lib 
| - --prefix=/opt/nlh --enable-shared
| 
| I use GNU Make 3.80.
| 
| Compilation failed in libcruft/misc as follows
| 
| cxx -c -I/opt/nlh/include -I. -I../.. -I../../liboctave -I../../src 
| - -I../../libcruft/misc  -I../../glob -I../../glob -DHAVE_CONFIG_H -ieee -ieee 
| - -O3 -arch ev7 -tune ev7 quit.cc -o quit.o
| cxx: Error: quit.cc, line 40: declaration is incompatible with
|           "void (*octave_interrupt_hook)() C" (declared at line 90 of 
| "quit.h")
| void (*octave_interrupt_hook) (void) = 0;
| - -------^
| cxx: Error: quit.cc, line 41: declaration is incompatible with
|           "void (*octave_bad_alloc_hook)() C" (declared at line 91 of 
| "quit.h")
| void (*octave_bad_alloc_hook) (void) = 0;
| - -------^
| 
| I found the following hack around this:
| 
| 1. libcruft/misc/quit.cc compiles if the following lines (90-91) 
|    in libcruft/misc/quit.h are commented out:
| 
|    extern void (*octave_interrupt_hook) (void);
|    extern void (*octave_bad_alloc_hook) (void);
| 
| 2. After these changes, src/toplev.cc no longer compiles.  toplev.cc does  
|    compile once those two lines are restored in quit.h.
| 
| Compilation then seems to get quite far, and creates an octave executable that 
| performs at least standard tasks (scalar and matrix arithmetic).
| 
| The make process fails again in directory src with
| 
| cxx -shared -Wl,-expect_unresolved -Wl,'*' -o kron.oct kron.o
| ld (prelink):
| so_locations: line #5: bad tag
| ld:
| so_locations: line #5: bad tag
| 
| The initial part of src/so_locations looks like this:
| 
| hess.oct \
| 		:st = .text 0x000003ffbffe0000, 0x0000000000020000:\
| 		:st = .data 0x000003ffffff0000, 0x0000000000010000:\
| 
| 000:\
| 
| besselj.oct \
| 		:st = .text 0x000003ffbf5a0000, 0x0000000000030000:\
| 		:st = .data 0x000003ffffc20000, 0x0000000000010000:\
| 
| After removing line 5, containing "000:\", the make process completed nicely, 
| and functions like eig() work as well.

I'm not sure what is causing the problem with so_locations, but I
think the other problems are fixed in 2.1.53.  If not, can you please
try the current CVS sources and see if there are still problem?

Thanks,

jwe
