#820: problem compiling a file with top level Template Haskell splice
---------------------------------+------------------------------------------
Reporter: guest | Owner:
Type: bug | Status: new
Priority: normal | Milestone: 6.4.2
Component: Template Haskell | Version: 6.4.2
Severity: normal | Keywords:
Os: Linux | Difficulty: Unknown
Architecture: x86_64 (amd64) |
---------------------------------+------------------------------------------
when compiling a file has both the following
a. a -package option that loads a package with ref to external library,
b. a top level Template Haskell splice $(...)
The compiler fails to load the library required by the package properly
and yields a failed compile due to 'unknown symbol'
I have a simple example that refers to the JRegex package, which loads
libpcre.so. The compile fails when compiling UseTH.hs, which refers to the
package JRegex, and has a top level splice.
Regex is available with cabalized build setup at
http://repetae.net/john/computer/haskell/JRegex/
and is trivial to install.
It is simple to get around the problem, as 'make separate' does here by
eliminating the dependency on the package in the file that splices but in
case someone else has this problem it doesn't hurt to have it documented.
