Hello,<br><br>My program keeps throwing this error after I created a child process with MPI_comm_spawn:<br><br><i>./../../Desktop/computacaoDistribuida/src/server/server: symbol lookup error: ./../../Desktop/computacaoDistribuida/src/server/server: undefined symbol: MPI_Send</i><br>

<br>I&#39;ve already used MPI_Send on other parts of the program...<br>I&#39;ve tried to print the message recieved from child process, but a similar message appears:<br><br><i>./../../Desktop/computacaoDistribuida/src/server/server: symbol lookup error: ./../../Desktop/computacaoDistribuida/src/server/server: undefined symbol: printf, version GLIBC_2.0<br>

<br></i>This printf is executed if MPI_Comm_spawn returned MPI_SUCESS, so I guess this is working.<br><br>It appears that my libs (glibc, mpi) were unload after the MPI_comm_spawn.<br><br>Does anyone knows what&#39;s this??<br>
