I am unable to link the cryptopp.dll on Windows XP Pro using cygwin and
gcc. I followed the steps below and hacked my through 80% of the build.
I am stuck on the cryptest.import.exe target.
Downloaded Cygwin with all packages except for the desktop, game,
multimedia, and graphic packages.
-----------------
$ g++ -v

gcc version 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
-----------------
Downloaded Crypto++ v5.4 ZIP file.
Run CygWin Shell (C:\cygwin\cygwin.bat).
Unzipped cryptopp54.zip using cygwin's unzip -a into
~/Docs/Projects/Crypto++/dev/src folder.
(make complained about being unable to build the modexppc.h output.)
Created "empty" C++ file for modexppc.cpp using example on the web.
-------------------------------------------
#include "pch.h"
#ifndef CRYPTOPP_IMPORTS
#include "modexppc.h"
#include "asn.h"
NAMESPACE_BEGIN(CryptoPP)
NAMESPACE_END
#endif
-------------------------------------------
(Many comments on the web suggested trying to build in release mode.)
Changed GNUmakefile as follows
Uncommented lines:
CXXFLAGS = -O3 -DNDEBUG -ffunction-sections -fdata-sections
LDFLAGS += -Wl,--gc-sections
(The other targets were unable to link in the pssr and emsa2 objects.)
Changed line
DLLSRCS = algebra.cpp algparam.cpp asn.cpp basecode.cpp

(I saw some updates in the CVS repository.)
Loaded CVS repository and copied file changes into the src folder.
(20061225 files)
(I'm runing cygwin.)
rm *.vcproj
rm *.bdsproj *.bdsgroup
I am able to make the cryptest.exe target by running make without any
parameters. I am also able to run the "./cryptest v" test and it
passes. When I try to create the cryptopp.dll it fails to link. It
fails when making the cryptest.import.exe target. I use the make
command:
$ make clean dll
I am getting over 4000 "undefined reference to" errors. The first dozen
errors look like:

Any help would be great.
