Unable to compile bitcoin

[corge]

I thought I would try bitcoin but I am unable to compile the latest bitcoin client (bitcoin-0.3.24).

I'm using 32-bit Slackware 13.1.0. When I initially attempted to compile I got errors related to wxWidgets being missing. This was resolved by compiling and installing wxWidgets. However I still get the following error:

g++ -c -O2 -Wno-invalid-offsetof -Wformat -g -D__WXDEBUG__ -DNOPCH -DFOURWAYSSE2 -DUSE_SSL -DUSE_UPNP=0 -I/usr/local/lib/wx/include/gtk2-unicode-2.9 -I/usr/loal/include/wx-2.9 -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL -D__WXGTK__ -pthread -DGUI -o obj/util.o util.cpp
In file included from main.h:11,
                 from headers.h:96,
                 from util.cpp:4:
db.h: In member function 'bool CDB::Exists(const K&)':
db.h:149: error: 'class Db' has no member named 'exists'
make: *** [obj/util.o] Error 1

I have tried to grep for the class definition of "Db" but I am unable to find it. Where is it? Is this a programming error from the developers of bitcoin, or is this a particular issue at my system?

However, most importantly, if there is a solution for this problem then please tell me.

I also tried simply running the binary that was distributed with the package, but that resulted in the following error:

./bitcoin: symbol lookup error: ./bitcoin: undefined symbol: gtk_widget_get_realized

On the bitcoin forum I was told the following

You might need libdb4.8++-dev or something like it.

I've been trying this for a few hours now. I downloaded libdb4.8-dev_4.8.24-1ubuntu1_i386.deb from Ubuntu -- Package Download Selection -- libdb4.8-dev_4.8.24-1ubuntu1_i386.deb. Converted it to TGZ with Alien and installed it, then finally ran ldconfig.

The compilation still fails, but the compiler added one new line:

 /usr/include/db_cxx.h:796: error: 'DB_XIDDATASIZE' was not declared in this scope

The full compiler error is:

g++ -c -O2 -Wno-invalid-offsetof -Wformat -g -D__WXDEBUG__ -DNOPCH -DFOURWAYSSE2 -DUSE_SSL -DUSE_UPNP=0 -I/usr/local/lib/wx/include/gtk2-unicode-2.9 -I/usr/local/include/wx-2.9 -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL -D__WXGTK__ -pthread -DGUI -o obj/util.o util.cpp

Any ideas?

I might be making some progress here, I'm not sure.

I've been trying to follow the guide at (the PDF file) error: "class Db" has no member named "exists" - Atomic 3.0
I installed all of the dependencies and then tried to use the Makefile presented in the document. This however only resulted in errors from make -- not errors from the compiler. With an unspecified rule.

I was unable to modify the Makefile trivially so I made more than just a few modifications, this is my Makefile for bitcoin now:

DEPSDIR=/tmp/bitcoin/deps

INCLUDEPATHS= -I"$(DEPSDIR)/include"
LIBPATHS= -L"$(DEPSDIR)/lib"
WXLIBS=$(shell $(DEPSDIR)/bin/wx-config --libs --static)
WXBASELIBS=$(shell $(DEPSDIR)/bin/wx-config --libs base --static)

LIBS= -dead_strip \

 $(DEPSDIR)/lib/libboost_system.a \

 $(DEPSDIR)/lib/libcrypto.a

WXDEFS=$(shell $(DEPSDIR)/bin/wx-config --cxxflags) -DNOPCH
DEBUGFLAGS=-g -DwxDEBUG_LEVEL=0
CFLAGS=-O2 -Wno-invalid-offsetof -Wformat $(DEBUGFLAGS) $(WXDEFS) $(INCLUDEPATHS)

bitcoind : $(OBJS:obj/%=obj/nogui/%) obj/sha.o
	g++ $(CFLAGS) -o $@ $(LIBPATHS) $^ $(WXBASELIBS) $(LIBS)

clean :
	-rm -f bitcoin bitcoind
	-rm -f obj/*
	-rm -f obj/nogui/*
	-rm -f headers.h.gch

This at least does not stop prior to compilation even starting (unlike the previously mentioned Makefile). However I get the following compiler errors:

ui.cpp:19: error: expected constructor, destructor, or type conversion before '(' token
ui.cpp:22: error: expected constructor, destructor, or type conversion before '*' token
ui.cpp:24: error: 'wxLocale' does not name a type
