Hi All, i had installed EntireX(Trial Version 6.2.1) on my Linux(running RedHat 7.3) Machine. when i tried to build “Hello RPC” Application provided by EntireX, i got the following error. =============================================== [hello@root]#make (cd unix ; make -f makefile) make[1]: Entering directory `/opt/sag/exx/v621/examples/msrpc/hello/server/unix'

Hello Ramesh, If you take a look at [http://www.softwareag.com/entirex/download/download\_entxDCOM.htm#Requirements%20to%20install](http://www.softwareag.com/entirex/download/download_entxDCOM.htm#Requirements%20to%20install) it says that the prerequisite glibc is v2.2.2 and I see that in your case you are linking againest v2.1.2. So I suspect this may be the cause of the link problem. Is is possible to install glibc v222? Hope this helps. Stuart Fyffe-Collins Software AG (UK) Ltd. ---

Hello, the released version of 6.2.1 will not run on RH 7.3. We had a customer who already noticed that, but in the end he didn’t wanted a patch cause he used 6.1.1. We can exchange getpwent\_r with getpwent (it is not critical in this case) and then it should run. Currently I don’t know how I can handle that with trial versions (for customers we could create a hotfix). I will try to find out if there is a way to provide some updated binaries.

Hello, we will not have any updates for the 6.2.1 trial version. Version 7.1.1 will be available for download in November. Regards, Volker Denkhaus ---
