GHC 6.2.1 compilation fails when compiling FFI code with -prof or -O2

Wed Apr 21 12:03:09 EDT 2004

I have an FFI program which compiles fine with GHC 6.2.1 under standard
compilation options (i.e. no optimisation etc), but not with -O2 or -prof.
With -prof/-O2 GHC compiles via C, and this seems to be causing the problem.

With -prof I get these error messages:

Compiling Database.Oracle.OCIFunctions ( ./Database/Oracle/OCIFunctions.lhs,
./Database/Oracle/OCIFunctions.o )
C:/TEMP/ghc202.hc:5:17: oci.h: No such file or directory
C:/TEMP/ghc202.hc: In function `r2Zg_entry':

C:/TEMP/ghc202.hc: In function `r2Zi_entry':
C:/TEMP/ghc202.hc:337: warning: implicit declaration of function
`OCIStmtExecute'
...etc...

With -O2 I get these:

Compiling Database.Oracle.OCIFunctions ( ./Database/Oracle/OCIFunctions.lhs,
./Database/Oracle/OCIFunctions.o )

...etc...

I've used these command line options for normal (no -prof or -O)
compilation:
 -Lc:\orant817\bin -loci

The "oci.h" file in question is located in c:\orant817\oci\include, and
oci.dll is located in c:\orant817\bin. When I compiled with -prof I tried
adding -#include c:\orant817\oci\include\oci.h, but this produces the output
below, where files included by oci.h can't be found. The oci.h file is at
the root of quite a large .h include tree; do I have to specify every .h
file in this tree with -#include?

My ghc command:
  ghc -v -Wall  -ddump-hi -prof  -Lc:\orant817\bin -loci -#include
c:\orant817\oci\include\oci.h -fasm -o ociffi --make Main.lhs
