You need to install the thrift compiler from
https://github.com/apache/thrift/releases
For linux/osx you download the .tar distro, and untar it, and then
./bootstrap.sh ./configure --disable-libs make sudo make install
If its succesful, you can type
thrift --version
To display the version of the thrift compiler.
You then need to compile the sample test source for the camel-thrift component.
The sample test source is an example taken from the Thrift Java tutorial at: https://thrift.apache.org/tutorial/java
cd components/camel-thrift cd src/test/thrift thrift -r --gen java -out ../java/ ./tutorial-dataformat.thrift thrift -r --gen java -out ../java/ ./tutorial-component.thrift
The generate source code will override the existing.
