Note that gcc and OCaml are configured for x86 (32 bits) not x86_64 (64 bits).
Could this be a 32-bit app / 64-bit system call compatibility issue?

It would be helpful to identify which system call fails. Something like

truss boot/ocamlrun boot/ocamllex parsing/linenum.mll

should show a trace of system calls.

Consider also compiling ocamlrun in debug mode (see INSTALL file) and
running byterun/ocamlrund under a debugger with arguments boot/ocamllex parsing/linenum.mll.

It is indeed a 32/64 bit issue, as ocaml compiles and installs just fine on another Solaris 10 machine running on an AMD Athlon XP (32 bit).

I am attaching the results of truss.

I manage to build using:

configure -cc "/usr/sfw/bin/gcc -m64" -host x86_64-solaris10 -with-pthreads

(after having patched configure with the patch attached so it recognizes /usr/sfw/bin/gcc as gcc to supply -fPIC instead of -KPIC, and so it uses amd64 as the target instead of ia32).

I cannot build "make opt" yet, as compilation of amd64.S aborts with the following error message:

/usr/sfw/bin/gcc -m64 -I../byterun -DCAML_NAME_SPACE -DNATIVE_CODE -DTARGET_amd64 -DSYS_solaris -O -D_FILE_OFFSET_BITS=64 -D_REENTRANT -c -o unix.o unix.c
gcc -c -DSYS_solaris -o amd64.o amd64.S ||

Changing ASPP with yet another patch to configure (attached configure2.txt supersedes configure.txt) so it uses /usr/sfw/bin/gcc instead of just gcc will get amd64.o to compile. The build fails downstream, presumably because ocamlopt is not calling the right assembler or giving it the right options (e.g. -xarch=amd64 if using Solaris /usr/ccs/bin/as).

There are two separate issues here:

1- The close() system call that returns EINVAL (see the truss output).
This is a Solaris bug: close() is not even allowed to ever return EINVAL
according to the Single Unix Specification.

2- The Solaris compilers appear to produce 32-bit apps by default and to require special options to produce 64-bit apps. This is OK except that OCaml's configuration makes it hard or even impossible to select the options appropriate for a 64-bit app. I might look into this later when I get access to a Solaris/AMD64 platform.
