# CMake in ClickHouse
|
||||
|
||||
How to make ClickHouse compile and link faster. Minimal ClickHouse build example:
|
||||
|
||||
```bash
|
||||
cmake .. \
|
||||
-DCMAKE_C_COMPILER=$(which clang-13) \
|
||||
-DCMAKE_CXX_COMPILER=$(which clang++-13) \
|
||||
-DCMAKE_BUILD_TYPE=Debug \
|
||||
-DENABLE_CLICKHOUSE_ALL=OFF \
|
||||
-DENABLE_CLICKHOUSE_SERVER=ON \
|
||||
-DENABLE_CLICKHOUSE_CLIENT=ON \
|
||||
-DENABLE_LIBRARIES=OFF \
|
||||
-DUSE_UNWIND=ON \
|
||||
-DENABLE_UTILS=OFF \
|
||||
-DENABLE_TESTS=OFF
|
||||
```
|
||||
|
||||
## CMake files types
|
||||
|
||||
1. ClickHouse's source CMake files (located in the root directory and in /src).
|
||||
2. Arch-dependent CMake files (located in /cmake/*os_name*).
|
||||
3. Libraries finders (search for contrib libraries, located in /contrib/*/CMakeLists.txt).
|
||||
4. Contrib build CMake files (used instead of libraries' own CMake files, located in /cmake/modules)
|
||||
|
||||
## List of CMake flags
|
||||
- The flag name is a link to its position in the code.
|
||||
- If an option's default value is itself an option, it's also a link to its position in this list.

## Developer's guide for adding new CMake options
|
||||
|
||||
#### Don't be obvious. Be informative.
|
||||
|
||||
Bad:
|
||||
|
||||
```
|
||||
option (ENABLE_TESTS "Enables testing" OFF)
|
||||
```
|
||||
|
||||
This description is quite useless as it neither gives the viewer any additional information nor explains the option purpose.
|
||||
|
||||
Better:
|
||||
|
||||
```
|
||||
option(ENABLE_TESTS "Provide unit_test_dbms target with Google.test unit tests" OFF)
|
||||
```
|
||||
|
||||
If the option's purpose can't be guessed by its name, or the purpose guess may be misleading, or option has some
|
||||
pre-conditions, leave a comment above the option() line and explain what it does.
|
||||
The best way would be linking the docs page (if it exists).
|
||||
The comment is parsed into a separate column (see below).
|
||||
|
||||
Even better:
|
||||
|
||||
```
|
||||
# implies ${TESTS_ARE_ENABLED}
|
||||
# see tests/CMakeLists.txt for implementation detail.
|
||||
option(ENABLE_TESTS "Provide unit_test_dbms target with Google.test unit tests" OFF)
|
||||
```
|
||||
|
||||
#### If the option's state could produce unwanted (or unusual) result, explicitly warn the user.
|
||||
|
||||
Suppose you have an option that may strip debug symbols from the ClickHouse's part.
|
||||
This can speed up the linking process, but produces a binary that cannot be debugged.
|
||||
In that case, prefer explicitly raising a warning telling the developer that he may be doing something wrong.
|
||||
Also, such options should be disabled if applies.
|
||||
|
||||
Bad:
|
||||
|
||||
```
|
||||
option(STRIP_DEBUG_SYMBOLS_FUNCTIONS
|
||||
"Do not generate debugger info for ClickHouse functions.
|
||||
${STRIP_DSF_DEFAULT})
|
||||
|
||||
if (STRIP_DEBUG_SYMBOLS_FUNCTIONS)
|
||||
target_compile_options(clickhouse_functions PRIVATE "-g0")
|
||||
endif()
|
||||
```
|
||||
|
||||
Better:
|
||||
|
||||
```
|
||||
# Provides faster linking and lower binary size.
|
||||
# Tradeoff is the inability to debug some source files with e.g. gdb
|
||||
# (empty stack frames and no local variables)."
|
||||
option(STRIP_DEBUG_SYMBOLS_FUNCTIONS
|
||||
"Do not generate debugger info for ClickHouse functions."
|
||||
${STRIP_DSF_DEFAULT})
|
||||
|
||||
if (STRIP_DEBUG_SYMBOLS_FUNCTIONS)
|
||||
message(WARNING "Not generating debugger info for ClickHouse functions")
|
||||
target_compile_options(clickhouse_functions PRIVATE "-g0")
|
||||
endif()
|
||||
```
|
||||
|
||||
#### In the option's description, explain WHAT the option does rather than WHY it does something.
|
||||
The WHY explanation should be placed in the comment. You may find that the option's name is self-descriptive.
|
||||
|
||||
Bad:
|
||||
|
||||
```
|
||||
option(ENABLE_THINLTO "Enable Thin LTO. Only applicable for clang. It's also suppressed when building with tests or sanitizers." ON)
|
||||
```
|
||||
|
||||
Better:
|
||||
|
||||
```
|
||||
# Only applicable for clang.
|
||||
# Turned off when building with tests or sanitizers.
|
||||
option(ENABLE_THINLTO "Clang-specific link time optimisation" ON).
|
||||
```
|
||||
|
||||
#### Don't assume other developers know as much as you do.
|
||||
In ClickHouse, there are many tools used that an ordinary developer may not know. If you are in doubt, give a link to
|
||||
the tool's docs. It won't take much of your time.
|
||||
|
||||
Bad:
|
||||
|
||||
```
|
||||
option(ENABLE_THINLTO "Enable Thin LTO. Only applicable for clang. It's also suppressed when building with tests or sanitizers." ON)
|
||||
```
|
||||
|
||||
Better (combined with the above hint):
|
||||
|
||||
```
|
||||
# https://clang.llvm.org/docs/ThinLTO.html
|
||||
# Only applicable for clang.
|
||||
# Turned off when building with tests or sanitizers.
|
||||
option(ENABLE_THINLTO "Clang-specific link time optimisation" ON).
|
||||
```
|
||||
|
||||
Other example, bad:
|
||||
|
||||
```
|
||||
option (USE_INCLUDE_WHAT_YOU_USE "Use 'include-what-you-use' tool" OFF)
|
||||
```
|
||||
|
||||
Better:
|
||||
|
||||
```
|
||||
# https://github.com/include-what-you-use/include-what-you-use
|
||||
option (USE_INCLUDE_WHAT_YOU_USE "Reduce unneeded #include s (external tool)" OFF)
|
||||
```
|
||||
|
||||
#### Prefer consistent default values.
|
||||
CMake allows you to pass a plethora of values representing boolean true/false, e.g. 1, ON, YES, ....
|
||||
|
||||
Prefer the ON/OFF values, if possible.
