How to avoid LNK1201 Error Writing to Program Database?

Posted on 2003-11-04
Last Modified: 2013-12-03
I have a very large application built in MSDEV 6.0.
I seemed to have approached a size limit for the .pdb file.
(It is around 64M.)
I get the LNK1201 error every other time I build the app.
I have several Gig of available disk space, so that's not the issue.
Removing the existing .pdb seems to allow it to build.
Rebuilding the .pdb from scratch each time seems to fix it,
but it unfortunately takes a long time to link the app.
I started removing debug symbols from the app using the
/Zd compiler flag.

Can anybody confirm that this size limit exists in VC60?
Is it the same in 7.0?
Do you know of any better workarounds for this problem?

Also, strangely enough, a fellow developer here builds the same
exact app on a different machine, but has a much smaller .pdb file.
He has the same version of compiler & linker that I do.
What can explain this difference?

>>I seemed to have approached a size limit for the .pdb file.

Indeed - see;en-us;238875 ("PRB: C2471 or LNK1140 Error with PDB File Limits")

The following errors are normally related to running into the module and size limits when a program database (PDB) file is created (a PDB file contains information used by the debugger; the file has a .pdb extension):

Compiler Error:

C2471: cannot update program database
Linker Error:

LNK1140 "too many modules for program database; relink with /PDB:NONE"

Linker Error:

LNK1201: error writing to program database "c:\MSDEV\Projects\yourapp\Debug\yourapp.pdb"; check for insufficient disk space

>>Is it the same in 7.0?

The article states:

The information in this article applies to:
Microsoft Visual C++, 32-bit Enterprise Edition 5.0
Microsoft Visual C++, 32-bit Enterprise Edition 6.0
Microsoft Visual C++, 32-bit Professional Edition 5.0
Microsoft Visual C++, 32-bit Professional Edition 6.0
Microsoft Visual C++, 32-bit Learning Edition 6.0

There is a limit of 4096 modules (.obj files) in a PDB file. The file also has a total size limit of approximately 64 MB.

There are several ways to reduce the size of PDB files:
Build some of the source files with the /Zd switch (line numbers only).
Build some of the source files as separate dynamic-link libraries (DLLs) instead of static libraries.
Build some of the source files without debug information.
Try the compiler switch /Fd"myproject.pdb" (including the quotation marks).

This doesn't resolve the issue. It still exists in 2009. vs7.1 and 8.0 still has this issue. MS needs to fix their IDE software (C++).
