However,\nif such a class has static member functions, then simply writing\n`LOG()` will not work because name lookup will find the non-static\nmember function and no the global function, resulting in a compiler\nerror because the non-static member cannot be invoked without\nan object, and there is no object in a static member function.\n\nThis can be avoided by using `using libcamera::_log;`, thereby\nbringing the global declaration into the current scope.\n\nSigned-off-by: Barnabás Pőcze \n---\n src/libcamera/sensor/camera_sensor_raw.cpp | 8 +++++---\n src/libcamera/v4l2_device.cpp | 10 ++++++----\n 2 files changed, 11 insertions(+), 7 deletions(-)","diff":"diff --git a/src/libcamera/sensor/camera_sensor_raw.cpp b/src/libcamera/sensor/camera_sensor_raw.cpp\nindex ab75b1f82..b6f16f58a 100644\n--- a/src/libcamera/sensor/camera_sensor_raw.cpp\n+++ b/src/libcamera/sensor/camera_sensor_raw.cpp\n@@ -171,10 +171,12 @@ CameraSensorRaw::~CameraSensorRaw() = default;\n std::variant, int>\n CameraSensorRaw::match(MediaEntity *entity)\n {\n+\tusing libcamera::_log;\n+\n \t/* Check the entity type. */\n \tif (entity->type() != MediaEntity::Type::V4L2Subdevice ||\n \t entity->function() != MEDIA_ENT_F_CAM_SENSOR) {\n-\t\tlibcamera::LOG(CameraSensor, Debug)\n+\t\tLOG(CameraSensor, Debug)\n \t\t\t<< entity->name() << \": unsupported entity type (\"\n \t\t\t<< utils::to_underlying(entity->type())\n \t\t\t<< \") or function (\" << utils::hex(entity->function()) << \")\";\n@@ -199,7 +201,7 @@ CameraSensorRaw::match(MediaEntity *entity)\n \t\t\tbreak;\n \n \t\tdefault:\n-\t\t\tlibcamera::LOG(CameraSensor, Debug)\n+\t\t\tLOG(CameraSensor, Debug)\n \t\t\t\t<< entity->name() << \": unsupported pad \" << pad->index()\n \t\t\t\t<< \" type \" << utils::hex(pad->flags());\n \t\t\treturn { 0 };\n@@ -207,7 +209,7 @@ CameraSensorRaw::match(MediaEntity *entity)\n \t}\n \n \tif (numSinks < 1 || numSinks > 2 || numSources != 1) {\n-\t\tlibcamera::LOG(CameraSensor, Debug)\n+\t\tLOG(CameraSensor, Debug)\n \t\t\t<< entity->name() << \": unsupported number of sinks (\"\n \t\t\t<< numSinks << \") or sources (\" << numSources << \")\";\n \t\treturn { 0 };\ndiff --git a/src/libcamera/v4l2_device.cpp b/src/libcamera/v4l2_device.cpp\nindex 2f65a43a0..8fda38949 100644\n--- a/src/libcamera/v4l2_device.cpp\n+++ b/src/libcamera/v4l2_device.cpp\n@@ -989,6 +989,8 @@ template std::optional V4L2Device::toColorSpace(const struct v4l2_mb\n template\n int V4L2Device::fromColorSpace(const std::optional &colorSpace, T &v4l2Format)\n {\n+\tusing libcamera::_log;\n+\n \tv4l2Format.colorspace = V4L2_COLORSPACE_DEFAULT;\n \tv4l2Format.xfer_func = V4L2_XFER_FUNC_DEFAULT;\n \tv4l2Format.ycbcr_enc = V4L2_YCBCR_ENC_DEFAULT;\n@@ -1017,7 +1019,7 @@ int V4L2Device::fromColorSpace(const std::optional &colorSpace, T &v\n \tif (itPrimaries != primariesToV4l2.end()) {\n \t\tv4l2Format.colorspace = itPrimaries->second;\n \t} else {\n-\t\tlibcamera::LOG(V4L2, Warning)\n+\t\tLOG(V4L2, Warning)\n \t\t\t<< \"Unrecognised primaries in \"\n \t\t\t<< ColorSpace::toString(colorSpace);\n \t\tret = -EINVAL;\n@@ -1027,7 +1029,7 @@ int V4L2Device::fromColorSpace(const std::optional &colorSpace, T &v\n \tif (itTransfer != transferFunctionToV4l2.end()) {\n \t\tv4l2Format.xfer_func = itTransfer->second;\n \t} else {\n-\t\tlibcamera::LOG(V4L2, Warning)\n+\t\tLOG(V4L2, Warning)\n \t\t\t<< \"Unrecognised transfer function in \"\n \t\t\t<< ColorSpace::toString(colorSpace);\n \t\tret = -EINVAL;\n@@ -1037,7 +1039,7 @@ int V4L2Device::fromColorSpace(const std::optional &colorSpace, T &v\n \tif (itYcbcrEncoding != ycbcrEncodingToV4l2.end()) {\n \t\tv4l2Format.ycbcr_enc = itYcbcrEncoding->second;\n \t} else {\n-\t\tlibcamera::LOG(V4L2, Warning)\n+\t\tLOG(V4L2, Warning)\n \t\t\t<< \"Unrecognised YCbCr encoding in \"\n \t\t\t<< ColorSpace::toString(colorSpace);\n \t\tret = -EINVAL;\n@@ -1047,7 +1049,7 @@ int V4L2Device::fromColorSpace(const std::optional &colorSpace, T &v\n \tif (itRange != rangeToV4l2.end()) {\n \t\tv4l2Format.quantization = itRange->second;\n \t} else {\n-\t\tlibcamera::LOG(V4L2, Warning)\n+\t\tLOG(V4L2, Warning)\n \t\t\t<< \"Unrecognised quantization in \"\n \t\t\t<< ColorSpace::toString(colorSpace);\n \t\tret = -EINVAL;\n","prefixes":["v1","2/3"]}
