If you already built the package with a different prefix, make sure to run "make clean" before building again. +** Note for cross-compiling ** + + The makefiles normally invoke the protoc executable that they just + built in order to build tests. When cross-compiling, the protoc + executable may not be executable on the host machine. In this case, + you must build a copy of protoc for the host machine first, then use + the --with-protoc option to tell configure to use it instead. For + example: + + ./configure --with-protoc=protoc + + This will use the installed protoc (found in your $PATH) instead of + trying to execute the one built during the build process. You can + also use an executable that hasn't been installed. For example, if + you built the protobuf package for your host machine in ../host, + you might do: + + ./configure --with-protoc=../host/src/protoc + + Either way, you must make sure that the protoc executable you use + has the same version as the protobuf source code you are trying to + use it with. + ** Note for Solaris users ** Solaris 10 x86 has a bug that will make linking fail, complaining |
