C code for Gembuilder For C

Gustav,

Here'sthe answer from engineering:

  The warnings about undefined Gci*   symbols is normal.

  Those functions are resolved at runtime after one of the  $GEMSTONE/lib/libgci*.so  

  library is loaded.  The library load is normally accomplished by

  calling  GciRtlLoad   or GciTsLoad  from your application's initialization code .

  See comments on gcirtl.hf for GciRtlLoad and GciTsLoad

  The "default path" is  $GEMSTONE/lib  

  libpam0g-dev is an appropriate package .

  If using the thread-safe GCI library ,  include  gcits.hf instead of gci.hf 

  and call GciTsLoad instead of GciRtlLoad .

Hallo

I am new to gemstone and still leaning c.

I am writing c code for gembuilder for c.

I wrote a c program that includes gci.hf and gcirtl.hf as specified  in the GemBuilder for C documentation.

I am using Ubuntu 16.04.1 LTS 64bit, GemStone/S 64 Bit v3.3.3. I use gcc/g++ version 5.4.0 20160609 to compile the code.

I am using the next commands to compile the code.

Compile c code:
$ g++ -fmessage-length=0 -fcheck-new -O3 -ggdb -m64 -pipe -D_REENTRANT -D_GNU_SOURCE -pthread -fPIC -fno-strict-aliasing -fno-exceptions -I/opt/gemstone/GemStone64Bit3.3.3-x86_64.Linux/include -x c++ -c userCode.c -o userCode.o

Link c objects:
$ g++ userCode.o $GEMSTONE/lib/gcirtlobj.o -Wl,-traditional -Wl,--warn-unresolved-symbols -m64 -lpthread -lcrypt -ldl -lc -lm -lrt -lpam -lpam_misc -Wl,-z,muldefs -o userAppl

Can you please help me by giving some suggestions on debugging the code?

When I compile and link the c code I get the following warnings:
/opt/gemstone/GemStone64Bit3.3.3-x86_64.Linux/lib/gcirtlobj.o: In function `GciTravBufHolder::free()':
/export/derby1/users/buildgss/33/build40760/src/gcicpp.hc:61: warning: undefined reference to `GciFree'

/export/derby1/users/buildgss/33/build40760/src/gcicpp.hc:45: warning: undefined reference to `GciHostCallDebuggerMsg'

How do I go about addressing these warnings?

I had some problems importing the pam libs, the system could not locate them. I installed libpam0g-dev this solved the problem. Should I have done something else?

Are there any more libs that is recommended to install?

Any pointers and advice will be appreciated.

Thanking you in advance

Gustav
