Hi,
I just installed ocaml-3.05. Compiling and installation worked
without any complains. However, I am having problems linking with
dynamic libraries.
hansr [4] [11:29] [~] ocamlmktop -o mytop nums.cma
Error on dynamically loaded library: /usr/local/lib/ocaml/dllnums.so: undefined symbol: custom_compare_default
hansr [5] [11:30] [~] ocamlmktop -o mytop str.cma
Error on dynamically loaded library: /usr/local/lib/ocaml/dllstr.so: undefined symbol: custom_compare_default
hansr [6] [11:37] [~] ocaml
Objective Caml version 3.05
# #load "str.cma";;
Cannot load required shared library: /usr/local/lib/ocaml/dllstr.so: undefined symbol: custom_compare_default.
#
etc....
The OS is RedHat 7.1. Two different system have been tried. One
using gcc 2.96 and the other gcc 3.04.
Ocaml-3.04 does have these problems.
Any suggestions on what I might be doing wrong?
Best regards,
Hans Ole Rafaelsen

I conjecture you have old files lying around in /usr/local/lib/ocaml.

In switching versions around, having to reinstall is a pain. Can't Ocaml 3.05 use a completely new set of directories so it can be installed without clobbering 3.04? -- John Max Skaller, mailto:skaller@ozemail.com.au snail:10/1 Toxteth Rd, Glebe, NSW 2037, Australia. voice:61-2-9660-0850 ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners ^ permalink raw reply [flat|nested] 6+ messages in thread

I guess yes, and you can easily use one of the configuration options to have ocaml installed in ocaml_3.05 (libdir, i think it is, but you could also use prefix /usr/local/ocaml_3.05 i think).

It's not clear how to manage binaries. What Python does is have 'python1.5' and 'python2.1' both in /usr/local/bin, and then use a symbolic link. Client can also put symlinks in ~/bin. Not clear to me how to ensure all binaries are switched around when changing versions. Same applies to man pages. At present, I just reinstall the version I want to use..which takes considerable time. Luckily, I only use optimising compiler, so once a binary is built, it matter not which development system is active .. but this won't be so once shared libraries are used .. Anyhow, just a though.. version control is a non-trivial thing. -- John Max Skaller, mailto:skaller@ozemail.com.au snail:10/1 Toxteth Rd, Glebe, NSW 2037, Australia. voice:61-2-9660-0850 ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners ^ permalink raw reply [flat|nested] 6+ messages in thread

Well, you build with : ./configure -prefix /usr/local/ocaml/3.05 ... and everything will go into the right place. Then you can build with : ./configure -prefix /usr/local/ocaml/3.06 ... for the next version, and : ocamlc -where will show the right place, which most packages use to know where to install stuff. Then you only need to have s symlink like : ln -s /usr/local/ocaml/3.05 /usr/local/ocaml/current or something, and have /usr/local/ocaml/current/bin in your PATH, and all will work as you want (unless i badly misunderstood you). This has worked since the early times of caml-light (well no the prefix option, but you could hand specify the libdir, bindir, etc ...).
