PRPNet Build Errors on Linux

[Happy5214]

Hi. I've tried numerous times to build PRPNet on Linux, with no success. The error message says that it cannot be linked. Any solutions? Trying to use PRPNet 5.0.7 on Kubuntu 11.10 (soon to be 12.04) x64.

Are you trying to build the client or the server or both? If you only need the client, then use "make prpclient" instead of "make". If you need the server, i.e. "make prpserver", then you need iodbc or some other odbc library that work with MySQL or PostgreSQl. Please report the text from your failed build so that I know what library is missing.

I am trying to build both the server and client.

This is the error (all the rest has already been compiled, I assume):

makeobj[0]: Entering directory `/home/happy5214/rps/prpnet/source'

Is there a package I need to install?

I don't think so. I saw something about adding -ldl to the link. I also saw something about adding -lpthread at the end. I suggest you google (as I did) unless someone here has more information. There are a number of linux users here, so one of them might be able to help.

Well, I got it to compile. The trick was to move the link parameters to the end of the command. Also, I had to link with unixodbc, as installing iodbc again would pretty much destroy my environment. It actually worked.

I then proceeded to run the server. I was even able to add candidates via the admin. But, the server can't read the candidates from the database at all. Apparently, the server uses the ifnull SQL function. However, that is not in the standard, thus my DB server, PostgreSQL, doesn't include it. I can't use MySQL because the ODBC config interface doesn't recognize it. (The driver uses version 5.1, while a recent upgrade left me with server version 5.5.) Any solutions?

Update the code to use "coalesce":

http://stackoverflow.com/questions/2...ent-for-isnull

If that works, I'll try to fix it in the next release.

[Happy5214]

It works. Thanks.

I have made changes to the makefile as Happy5214 stated:

CPP=g++ -I/usr/include -pthread -lodbc

CPPFLAGS=-c -O2 -Wall

# prpclient/prpadmin link flags
#LFLAGS_CLIENT=-lpthread -lstdc++ -o
LFLAGS_CLIENT=-o


# use this on most Unix systems for prpserver
#LFLAGS_SERVER=-lpthread -liodbc -lstdc++ -o
LFLAGS_SERVER=-o

I can now build a prpclient and a prpadmin. I keep getting errors for the prpserver.

I did the following:

make prpserver &> build_errors.txt

Attached is the makefile and build_errors.txt

Any advice would be greatly appreciated.

This was done on xubuntu 12.04 64-bit version.

The LFLAGS you are using are incorrect. Why did you change them? Happy5214 needed different flags because he is using unixodbc instead of iodbc. What happens if you use the default LFLAGS (-lpthread -liodbc -lstdc++ -o)?
